Question

A slide reaches a vertical height of 16 feet and makes an angle of 25° with the ground. How long is the slide

Answer 1

17.7 feet

Explanation:

law of sines:

x = length of slide

base of slide forms a 90 degree angle with the ground

to find the number of degrees in the third angle, subtract 115 from 180

sin 65°/16 = sin 90°/x

16 = sin 65°(x)

x = 16/(sin 65°) ≈ 17.7 feet
