In the triangle shown above, a = 16 cm, b= 12 cm, and c= 8 cm. What is the approximate measure of angle A?


A. 14.48°

B. 75.52°

C.65.56°

D.104.48°​

Answers

Answer:

I think its A

Step-by-step explanation:

The approximate measure of angle A is 104.48 degrees. The correct option is D.

Given that:

a = 16 cm

b = 12 cm

c = 8 cm

To find the measure of angle A in the triangle, use the law of cosines.

The law of cosines states that for any triangle with sides a, b, and c, and the angle opposite side c, denoted as C:

c² = a² + b² - 2ab × cos(C)

In this case, we want to find angle A, which is opposite side a. So, the equation becomes:

a² = b² +c² - 2bc × cos(A)

Now, plug in the given values:

16² = 12² + 8² - 2 × 12 × 8 × cos(A)

256 = 144 + 64 - 192 × cos(A)

Now, isolate cos(A):

192 × cos(A) = 144 + 64 - 256

192 × cos(A) = -48

cos(A) = -48 / 192

cos(A) = -1/4

Now, to find the measure of angle A, take the inverse cosine (cos^-1) of -1/4:

[tex]A \approx cos^{-1(-1/4)}[/tex]

A ≈ 104.48 degrees.

So, the approximate measure of angle A is 104.48 degrees. The correct option is D.

t = 0.06p

================================================

Explanation:

If we plugged in p = 2, then,

t = 0.06*p = 0.06*2 = 0.12

Showing that the point (2, 0.12) is on the diagonal line of the equation t = 0.06p

This matches with what the graph shows.

The y axis is incrementing by $0.025, aka 2.5 cents, each tickmark upward. Counting up 5 tickmarks will get you to $0.125 or 12.5 cents which is fairly close to 12 cents.

Answer:

y = -4x + 5

Step-by-step explanation:

choose 2 easy-to-read points on the line:  (0, 5) and (2, -3)

Because we have chosen the point that intersects the y-axis (0, 5) we know that the y-intercept of the line is 5.

Using equation of a line in slope-intercept form: y = mx + b (where m is the slope and b is the y-intercept):

The slope of the line = change in y ÷ change in x = (-3 - 5) ÷ (2 - 0) = -4

Therefore, y = -4x + 5

Angle measures:

a = x = z = 51° (as vertical angles and corresponding angles)b = d = y = w = 180° - 51° = 129° (as supplementary angles and corresponding angles)Part B

Supplementary angles for a linear pair and sum to 180°.

Examples are:

a and b or a and d orx and y etc.

Solution:

Given:

An angle which measures 51°

Using the given measure of an angle, we can identify all the angles.

a° = 51° (Vertically opposite angles)b° = 180 - 51 = 129° (180° angle)d° = b° = 129° (180° angle)w° = 129 (Alternate inner angles)x = a = 51° (Alternate inner angles)z = x = 51° (Vertically opposite angles)w = y = 129° 9 (vertically opposite angles)

We can tell that:

a = x = z = 51°b = d = w = y = 129°

Supplementary angles are pairs of angles that sums up to 180°.

Example of supplementary angle:

∠a and ∠b are supplementary angles because they sum up to 180°.

8. A study found that 72% (0.72) of people wear their seat belts? If three people
are selected at random, what is the probability that all three people wear their
seat belts?

Answers

Answer:

0.373248

Step-by-step explanation:

P(A and B) = P(A) * P(B)

Let's say one person wearing a seat belt is event A, the second person wearing a seat belt is event B, and the third person wearing their seat belt is event C

P(A and B and C) = P((A and B) and C) = (P(A) * P(B)) *P(C) = P(A) * P(B) * P(C)

The probability of each is 0.72. Our answer is therefore 0.72 * 0.72 * 0.72, or 0.72³ = 0.373248

I need 10-18 if you know any please help me out!!

Answers

Step-by-step explanation:

10.

angle QUR must be 180-41 = 139°

the reason : all angles on one side of the line QS around a single point (like U) must be 180°, as this represents a half-circle.

11.

the angle RUQ is larger.

the angle TUS is 90°.

therefore, SUN is 90° too. as well as TUQ and QUN.

the angle TUR is then TUS + 41 = 90+41 = 131°

and we know from 10. that QUR (or RUQ) is 139°.

therefore, RUQ is larger.

12.

when 2 lines cross, then the diagonally opposing angles are identical.

therefore,

84 = 4x

x = 21

13.

the same principle as in 10. applies.

all angles in one side of a line around a single point must be 180°.

so,

KMH + 84 = 180

KMH = 96°

14.

EBD = 90°

therefore, also ABE = 90°.

and we can imagine that BE extends straight to the other side of B having a point G there.

and then ABG = DBG = 90° as well.

and because these 90° angles and the principle of 12., we have

ABF = CBD = 90-62 = 28°

therefore,

CBE = CBD + DBE = 28 + 90 = 118°.

15.

ABF = 28°

as we calculated that in 14 already.

16.

due to the principles of 14 and 10 we have

CBA = 180 - CBD = 180 - 28 = 152°.

17.

this is not relevant to any of the pictures before.

angle A = angle B + 4

complementary angles are together 90°.

so,

A + B = 90

now we use the identity of the first equation in this main equation :

(B + 4) + B = 90

2B + 4 = 90

2B = 86

B = 43°

=>

A = B + 4 = 43 + 4 = 47°

18.

again, this is not related to any of the pictures before.

supplementary angles are together 180°.

D = 5E

D + E = 180

5E + E = 180

6E = 180

E = 30°

=>

D = 5E = 5×30 = 150°

Jaime needs to buy a new refrigerator for his apartment. He found what he needed for $1,300 at a well-known appliance store. The store is offering two options for Jaime to finance the appliance:

Option I: A store credit card with a $1,500 limit:

1) The credit card charges 16.5% annual interest rate.

2) The minimum monthly payment is $100 plus the monthly finance charge.

3) No down payment required

4) The loan is expected to be paid off in12 months to avoid additional penalties.





Option II: The appliance store offers an installment loan for his purchase:

1) Loan charges a simple interest rate of 12.5%.

2) Loan must be paid off in 12 equal payments to avoid penalties.

3) A $300 down payment is required.

Answers

Jamie should accept the second option to buy a new refrigerator for his apartment.

What is the annual interest rate?

The annual interest rate on an amount borrowed or a loan is the increment added to the loan at a particular rate over the desired period of time.

The objective of this question is to weigh the two options and determine the best means by which Jamie could get a new refrigerator for his apartment.

Option 1:

The annual interest rate for the first card = $1300 × 16.5%

The annual interest rate = $214.5

The minimum monthly payment is $100 plus the monthly finance charge.

The monthly finance charge on a credit card can be estimated by finding the average daily balance using the Annual interest rate and the days of the billing cycle.

The monthly finance charge [tex]\mathbf{=1300\times \dfrac{0.165}{12}}[/tex]

The monthly finance charge = $17.88

Now,

The minimum monthly payment is $100 + $17.88

The minimum monthly payment for the first month = $117.88

Provided there is no down payment;

In 12 months, Jaime would have paid off the loan with an additional interest of $214.5

Total amount paid = ($117.88 × 12)+$247.5

= $1629.06

Option 2.

The appliance store offers an Installment loan;

The loan charges a simple interest rate of 12.5%;

Using;

[tex]\mathbf{S.I = \dfrac{PRT}{100}}[/tex]

Since the loan must be paid in 12 equal payments, we can say the loan is paid monthly which is equivalent to 1 year.

i.e.

Time (T) = 1 year

[tex]\mathbf{S.I = \dfrac{1300 \times 12.5 \times 1}{100}}[/tex]

S.I = $162.5

Given that;

The down payment = $300

In the total amount of $1300, Jamie has an outstanding amount of $1000 to pay.

Thus, In 12 equal payment times,

Jamie gets to pay = $1000/12

Jamie gets to pay = $83.33 each time.

Total amount paid = $162.5 + 1300

Total amount paid = $1462.5

Therefore, we can conclude that Jamie should accept the second option to buy a new refrigerator for his apartment since the total amount paid in option 2 is lesser than that of option 1.
