To solve this problem you must apply the proccedure shown below:
1- The ladder forms an isosceles triangle, because it has two equal sides.
2- Let's call the angle
. To calculate it , you can divide the triangle into two equal right triangles and the angle
will be divided into two equal parts too. Therefore, you can calculate the half of the angle and then multiply it by two, as following:



The answer is:

Answer:
y - 8 = -2(x - 9)
Step-by-step explanation:
Given the slope, m = -2, and the point, (9, 8):
Let (x₁, y₁) = (9, 8)
slope (<em>m </em>) = -2
We can substitute these values into the following <u>point-slope form</u>:
y - y₁ = m(x - x₁)
y - 8 = -2(x - 9) ⇒ This is the point-slope form.
The first is C. r = 4(4/9)
the second one is B. h = 130
the second one is A. k = 7
