Question

A ladder is resting against a wall. the ladder and the ground make an angle of 39° and the ladder is 14 ft long. how far away from the wall is the ladder?

Answer 1

Let:

the ladder length = l
the distance from the wall and the ladder = x


cos (39) = x / l

x = l * cos (39) = 14 * cos (39) = 10.88 ft
