The triangle height is calculated by Pythagorean Theorem
height^2 = 15^2 - 9^^2
height^2 = 225 - 81
height^2 = 144
height = 12
We can calculate the value of Angle a
cosine (a) = adj / hyp = 9/15 = .6
arc cosine (a) = 53.13 degrees
angle b = 180 -90 -53.13
angle b = 36.87 degrees
tangent b = height / x
tangent 36.87 = 12 / x
x = 12 / .75
x = 16
Yes, it's just that "simple" LOL
Answer:
k=2.5
Step-by-step explanation:
7.6/2 = 3.8
9.5/3.8 = 2.5
Answer:
The answer is
<h2>12</h2>
Step-by-step explanation:
The above variation is written as

where k is the constant of variation
when y = 9
x = 4
We have
k = yx²
k = 9(4)²
k = 9 × 16
k = 144
So the formula for the variation is

when y = 1

Cross multiply
x² = 144
Find the square root of both sides
x = √144
x = 12
Hope this helps you.
Answer:
25.95 quarters which is about 6.5 years
Step-by-step explanation:
Get x by itself.
First add 11 to both sides:
5x = 45
Then divide both sides by 5:
x = 9
