Question

A 15-foot ladder leans against a building and makes a 61° angle with the ground. How far away is the base of the ladder from the base of the building? Round to the nearest tenth.

GPT-5 mini · Answer

Let the ladder be the hypotenuse. The horizontal distance x = 15 cos(61°).

x = 15 · cos(61°) ≈ 15 · 0.4849 ≈ 7.3 feet (to the nearest tenth).
