What is the measure of angle ABC?​

Answer:

Substitute the values given for f(x) and g(x), in 1. they say f(x)=4x and g(x)=1-x

and basically just substitute them for the functions themselves.

4x+1-x

add like terms!

4x-x = 3x!

3x+1 is your simplified answer, since it is an expression it cannot be simplified any further.

Answer:

x = 32

Step-by-step explanation:

(whole secant) x (external part) = (tangent)^2

(x+18) * 18 = 30^2

(x+18) * 18 = 900

Divide each side by 18

(x+18) * 18/18 = 900/18

(x+18)  = 50

Subtract 18 from each side

x+18-18 = 50-18

x=32

Answer:

50

Answer:

Divide the each part and get the circle 360 and triangle 180

Let's focus on the figure on the left.

For any quadrilateral, the angles always add up to 360. We'll use this to find x.

105+80+75+x = 360

260+x = 360

x = 360-260

x = 100

Now notice that the pair of adjacent angles 105 and 80 add up to 105+80 = 185, which is not 180. Similarly, the adjacent angles 80 and 75 add to 155 which is not 180.

This is enough to show that we don't have any parallel lines here. If we did have parallel lines, then adjacent angles would add to 180.

Since none of the lines are parallel, this figure is not a trapezoid

Any trapezoid has exactly one pair of parallel lines.

-------------------------------------------------------------------------------------

Move onto the figure on the right

We'll follow the same ideas mentioned in the last section.

x+110+92+88 = 360

x+290 = 360

x = 360-290

x = 70

Note how the adjacent angles 70 and 110 add to 70+110 = 180. This shows they are supplementary angles and that we do have a set of parallel lines (top and bottom). In contrast, the angles 110 and 92 do not add to 180, so that helps us see we only have one pair of parallel lines.

Therefore, the figure is a trapezoid

Answer:

4 1/12 yards of fabric left.

Step-by-step explanation:

First things first: convert the mixed numbers so they have the same denominator

The least common multiple of 4 and 3 is 12, so the common denominator will be 12.

So Jenna has 10 9/12, and uses 6 8/12.

Now subtract:

10 9/12 - 6 8/12 = 4 1/12

So there is 4 1/12 yards of fabric left.

Answer:

Step-by-step explanation:

2x+15+x+10+3x+5=180 degree(sum of interior angles of a triangle)

6x+30=180

6x=180-30

x=150/6

x=25

therefore the value of x is 25 degree.

Answer:

5 is 35 and 6 is 50

Step-by-step explanation:

To solve 5, you need to know how many degrees is the line, which is 180 because lines are 180 degrees. You then subtract 110 from 180 which equals to 70. What you have left now is 2k. A number times 2 will equal to 70, so k=35.

For 6, if you ever see two lines intersecting each other, it means that it is 360 degrees. We already have one angle, which is 120. The other angle is d+70 degrees, and any angle that is reflecting the other angle will have the same value. So, d equals 50

What is a irrationale number ?

Irrational number, any real number that cannot be expressed as the quotient of two integers. ... For example, there is no number among integers and fractions that equals the square root of 2.

An example : 1.234343 , [tex]\sqrt{9\\}[/tex] , π ...

Answer:

B

Step-by-step explanation:

The 45 45 90 triangle means that the hypotenuse is just one of the two legs multiplied by rad2. This means that leg s is 10.

The length of the leg is 10.

Option B is the correct answer.

There are three commonly used trigonometric identities.

Sin x = Perpendicular / Hypotenuse

Cosec = Hypotenuse / Perpendicular

Cos x = Base / Hypotenuse

Sec x = Hypotenuse / Base

Tan x = Perpendicular / Base

Cot x = Base / Perpendicular

We have,

Sin 45 = Opposite face to angle 45/ Hypotenuse

1/√2 = s / 10√2

s = 10√2 / √2

s = 10

Thus,

The length of the leg is 10.

I'll do the first one (on the left) to get you started.

Pick any two rows you want from the table. I'll pick the first and third rows.

These rows say that (2,-1) and (4,4) are points on the line.

Use the slope formula to get...

m = (y2-y1)/(x2-x1)

m = (4-(-1))/(4-2)

m = (4+1)/(4-2)

m = 5/2 is the slope

Answer:

Step-by-step explanation:

Lily paid $750 each month for 36 months to pay off her car loan.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example: so

1 + 3x + 4y = 7 is an expression.com

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

To calculate the amount that Lily paid each month, we can divide the total cost of the car by the number of monthly payments:

So,

Amount paid each month

= Total cost / Number of payments

In this case,

The total cost is $13,500 and the number of payments is 36:

Amount paid each month = $13,500 / 36

We can simplify this fraction by dividing both the numerator and the denominator by the greatest common factor of 13,500 and 36, which is 18:

Amount paid each month = $750

Therefore,

Lily paid $750 each month for 36 months to pay off her car loan.

Answer: 54

Step-by-step explanation:

Total votes: 240

Votes for the winner: x

Votes for candidate 1: x - 8

Votes for candidate 2: x - 13

Votes for candidate 3: x - 15

Equation to find the amount of votes of the winner (x) is:

240 = x +  x - 8 + x - 13 + x - 15

Combine x and x to get 2x.

240=2x−8+x−13+x−15

Combine 2x and x to get 3x.

240=3x−8−13+x−15

Subtract 13 from −8 to get −21.

240=3x−21+x−15

Combine 3x and x to get 4x.

240=4x−21−15

Subtract 15 from −21 to get −36.

240=4x−36

Swap sides so that all variable terms are on the left hand side.

4x−36=240

Add 36 to both sides.

4x=240+36

Add 240 and 36 to get 276.

4x=276

Divide both sides by 4.

x= 4/276  

Divide 276 by 4 to get 69.

x=69

Votes for the winner: 69

Votes for candidate 1: 69 - 8 = 61

Votes for candidate 2: 69 - 13 = 56

Votes for candidate 3: 69 - 15 = 54

The candidate that had the lowest number of votes received 54 votes.

The value of x in the given isosceles triangle, is √55 units.

A triangle with two sides equal is called an isosceles triangle.

Given that, an isosceles triangle, with base 6 units and legs 8 units, we need to find the length of the altitude x,

Since, ABC is an isosceles triangle, therefore, BD = DC = 6/2 = 3 units

Using the Pythagoras theorem,

AC² = DC² + AD²

8² = 3² + AD²

AD² = 64-9

AD² = 55

AD = √55

Hence, the value of x in the given isosceles triangle, is √55 units.
