Problema Solution

A ladder leaning against a hose makes an angle of 60° with the ground. The foot of the

ladder is 7 feet from the foot of the house. How long is the ladder?

Answer provided by our tutors

Let 'x' represent the length of the ladder.

cos(60) = 7/x

x = 7/cos(60)

x = 7/0.5

x = 14 ft

The ladder is 14 feet long.
