Question

A ladder leans against the side of a house. The angle of elevation of the ladder is 62˚ when the bottom of the ladder is 16ft from the side of the house. Find the length of the ladder. Round your answer to the nearest tenth.

Answer 1

The length of the ladder is about 34.1 feet.

Explanation:

cos(62°) = 16/h

h cos(62°) = 16

h = 16/cos(62°) = 34.1 feet
