(D) 33 feet
<u>Explanation:</u>
Given:
Height of the tree, h = 22 feet
angle, θ = 42°
Length of the ladder, l = ?
We know:
sin θ = Perpendicular / hypotenuse
So,
Sin θ = height of the tree / length of the ladder
![sin 42^0 = \frac{22}{l} \\\\0.67 = \frac{22}{l} \\\\l = 32.84 feet](https://tex.z-dn.net/?f=sin%2042%5E0%20%3D%20%5Cfrac%7B22%7D%7Bl%7D%20%5C%5C%5C%5C0.67%20%3D%20%5Cfrac%7B22%7D%7Bl%7D%20%5C%5C%5C%5Cl%20%3D%2032.84%20feet)
l = 32.84 feet ≈ 33 feet
Therefore, the length of the ladder be to reach the top of the apple tree is 33 feet.
