A ladder is leaning up against a 17 foot Wall at an angle of elevation of 37°. How far is the foot of the latter from the wall? Round your answer to the nearest 10th of a foot

This is the concept of trigonometry, the distance from the foot of the ladder will be given by:

tan theta=[opposite]/[adjacent]

opposite=17 ft

adjacent=x ft

theta=37°

thus

tan 37=17/x

x=17/tan 37

x=22.56 ft

=22.6 ft (to the nearest 10th of a foot)
