What is important when learning about trig?
Answer:
-You should already be familiar with algebra and geometry before learning trigonometry. From algebra, you should be comfortable with manipulating algebraic expressions and solving equations. From geometry, you should know about similar triangles, the Pythagorean theorem, and a few other things, but not a great deal.
-Measure the lengths of the sides of sets of similar right angled triangles and find the ratio of sides.
-Investigate the relationship between these ratios and the angle size.
-Use calculators or tables to find the sine, cosine and tangent of angles.
Step-by-step explanation:
basic knowledge i guess
Before beginning trigonometry, you need be comfortable with algebra and geometry. You should be comfortable handling algebraic expressions and solving problems after studying algebra. You should know about similar triangles, the Pythagorean theorem, and a few other things from geometry, but not much else. Students can use trigonometry to calculate the precise angle of a triangle's sides, the distance between distinct points on a triangle, and other information that is useful in a number of situations. Trigonometry is an essential component of ICSE Class 10 Mathematics since it combines memorization, conceptual knowledge, and problem-solving abilities. Because many of the earth's natural formations resemble triangles, it aids children in their comprehension of the globe.

what is x-72=136 and what is n - 10 = 13 + 5
Answer:
1) x = 208 2) n = 28
Hope this helps! Have a great day!!
Step-by-step explanation:
1)
x - 72 = 136
+ 72 +72
x = 208
2)
n - 10 = 13 + 5
n - 10 = 18
+10 +10
n = 28

Discuss the income effect for normal and inferior goods
Answer:
➢ The income effect describes the relationship between an increase in real income and demand for a good. The result of the income effect for a normal good is discernible to that of an inferior good in that a positive income change causes a consumer to buy more of a normal good, but less of an inferior good.

The x coordinate is zero and
the y coordinate is positive so what quadrant are they located in
Answer:
If the x-coordinate is (0,0) and the y-coordinate is positive, it is not technically in any quadrant because it is located on the line and not in any quadrant.

Some of the steps in Raya's solutions are shown.
Answer:
2. Distributive Property
4. Division Property of Equality
Step-by-step explanation:
2. The reason is Distributive Property since Raya distributed 2.5 to each term in the parentheses:
2.5(6.25x)+2.5(0.5)=11 --> 15.625x+1.25=11
4. The reason is Division Property of Equality since Raya divided both sides by 15.625.
A more in depth version of 3-4:
15.625x+1.25-1.25=11-1.25
15.625x=9.75
Divide both sides by 15.625 (division property of equality since she is dividing the same number from both sides of the equation)
x=0.624

On Saturday a local hamburger shop sold a combined total of 435 hamburgers and cheeseburgers the number of the cheeseburgers sold was two times the number of hamburgers sold how many hamburgers were sold on Saturday?
Answer:
145 Hamburgers were sold on Saturday
Step-by-step explanation:
435/3=145
145 x 2=290
290+145=435
Answer:
145 hamburgers
290 cheeseburgers
Step-by-step explanation:
let 'h' = # of hamburgers
let 'c' = # of cheeseburgers
h + c = 435
c = 2h
substitute '2h' for 'c' in the first equation:
h + 2h = 435
3h = 435
h = 145
c = 2(145) = 290
how to do subtracting unlike fractions easily?
Find the least common multiple of the denominators of the fractions. Write equivalent fractions that have the least common multiple as the denominator.
Urgent and pls explain thoroughly. O is the centre of the circle. OA, OB and OC are radii. Angle AOB = 72°.
Work out
a) angle OAB b) angle OCB c) angle ABC
Answer:
<ABC=90° <OCB=36° <OAB=54°
Step-by-step explanation:
<ABC=90°
<ocb= half of aob
<oab + <abc+<ocb=180°(triangle abc)
Answer:
a) ∠OAB = 54°
b) ∠OCB = 36°
c) ∠ABC = 90°
Step-by-step explanation:
a)
If O is the center of the circle, then OA and OB are both the radius. Therefore, OA = OB
This means that ΔAOB is an isosceles triangle, as is has two sides of equal length (OA and OB).
The angle between the equal sides (∠AOB) is called the vertex angle. The side opposite the vertex angle (AB) is called the base and base angles are equal. Therefore, ∠OAB = ∠OBA
Given:
The sum of the interior angles of a triangle is 180°∠AOB = 72°∠OAB = ∠OBA⇒ ∠OAB + ∠OBA + ∠AOB = 180
⇒ ∠OAB + ∠OBA + 72 = 180
⇒ ∠OAB + ∠OBA = 108
⇒ ∠OAB = 108 ÷ 2 = 54°
b)
Again, we can see that OB and OC are both the radius, so OB = OC. This means that ΔBOC is also an isosceles triangle, with ∠BOC as the vertex and BC as the base.
Calculate ∠BOC:
Given:
Angles on a straight line add up to 180°∠AOB = 72°⇒ ∠AOB + ∠BOC = 180
⇒ 72 + ∠BOC = 180
⇒ ∠BOC = 108°
Calculate ∠OCB:
Given:
The sum of the interior angles of a triangle is 180°∠BOC = 108°∠OBC = ∠OCB⇒ ∠OBC + ∠OCB + ∠BOC = 180
⇒ ∠OBC + ∠OCB + 108 = 180
⇒ ∠OBC + ∠OCB = 72
⇒ ∠OCB = 72 ÷ 2 = 36°
c)
Thales's theorem is a special case of the inscribed angle theorem and states that:
If A, B, and C are distinct points on a circle where the line AC is a diameter, then ∠ABC is a right angle.Given that AC is the diameter of this circle, and points A, B and C are on the circle, then ∠ABC = 90°

[1] y = 2x
- the line goes through the origin (0, 0) so there will be no b value
- the line, starting from (0, 0) goes up two and to the right 1 into the next point giving us a slope of 2/1 which simplifies to 2
[2] (0, 5)
- we can figure this out without graphing or plugging in values because (0, y) will be the y-intercept, or the b value
- in this case the value is 5
[3] y = 3x + 12
- it uses a different term than I am used too, but by "graident" I think they mean the slope
- if it has the same slope, then it will be a slope of 3
- if it passes through (0, 12) then again, this is the y-intercept or our b-value
Have a nice day!
-> See attached for more information on b values
I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly.

B. No, because 9*2 + 12*2 ≠ 15*2
C. No, because 9+ 12 ≠ 15.
D. Yes, because 9*2 + 12*2 > 15*2

Step-by-step explanation:
Describing a System of Equations
Describe a system of linear equations that has no solution.
Answer:
If a system has no solution, it is said to be inconsistent . The graphs of the lines do not intersect, so the graphs are parallel and there is no solution.
Answer:
Sample Response/Explanation: A system consisting of lines that do not intersect will have no solution. Lines will not intersect if they have the same slope, but different y-intercepts. Parallel lines have the same slope, which means they will never intersect.

4-(3x+3)=4x
The way I did was
4-3x+3=4x
Then i group the x
3x-4x=
Now that’s where I got stuck
Answer:
4-(3x+3)=4x
4-3x-3=4x
4-3=4x+3x
1=7x
x=1/7
or
4-(3x+3)=4x
4-3x-3=4x
-3x-4x=-4+3
-7x=-1
x=-1/-7
-/-=+
so -1/-7 it equal to 1/7
you dont want negative x
x=1/7
Answer:
1/7
Step-by-step explanation:
Take your equation: 4-(3x+3)=4x
Then, use the distributive property to carry out the negative sign, so you get 4-3x-3=4x
Add 3x to both sides to get: 4-3=4x+3x
Add like terms together to get: 1=7x
Flip the sides to get: 7x=1
Divide by 7 on both sides to get 7x/7=1/7
Simplify to get: x=1/7

S $1,595 deposit for 10 years at a simple interest rate of 8%
Answer:
$2,871.00
Step-by-step explanation:
Calculation:
First, converting R percent to r a decimal
r = R/100 = 8%/100 = 0.08 per year.
Solving our equation:
A = 1595(1 + (0.08 × 10)) = 2871
A = $2,871.00
The total amount accrued, principal plus interest, from simple interest on a principal of $1,595.00 at a rate of 8% per year for 10 years is $2,871.00.
