Question

A 20 foot ladder is leaning against the outside of the house while a painter is painting. The ladder makes an angle of 72 with the ground. What is the distance between the foot of the ladder and the house? Round your answer to the nearest foot.

Answer 1

Answer:19

Step-by-step explanation:

since the angle is 72° and the ladder is 20 foot, then our hypothenus side is 20foot and we are to find the opposite side of the triangle.

Sinθ = opp/ hyp

Sin72° = opp/20

cross multiply

Opp = 20 × sin 72°

= 20 × 0.951

=19.02

=19 to the nearest foot.
