Guyyysss.. :) Help me solve this geometry problem

Lerok [7]

Answer:

The question asks arc length:

$\frac{ \frac{ \frac{2\pi}{3} }{2\pi} }{1} = \frac{1}{3}$

Dividing by

$2\pi$

Because 360°(by formula)

Therefore:

$\frac{1}{3} \times \frac{2\pi \times 8}{1} = \frac{16\pi}{3 } = 5 \ \frac{\pi}{3} \\ so \: arc \: length \: = \frac{16\pi}{3}$

Good luck!

A ladder leans against a 22-feet-tall apple tree. The base of the ladder forms a 42° angle with the ground. Approximately how ta

igomit [66]

(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

$sin 42^0 = \frac{22}{l} \\\\0.67 = \frac{22}{l} \\\\l = 32.84 feet$

l = 32.84 feet ≈ 33 feet

Therefore, the length of the ladder be to reach the top of the apple tree is 33 feet.
