Question

A bird is perched on a tree branch that is 23 feet tall. The diagonal distance between you and the bird is 28 feet. You are 5.5 feet tall. What is the angle of elevation you use to look at the bird? A. 50. B. 55. C. 39. D. 11.

GPT-5 mini · Answer

Vertical difference = 23 − 5.5 = 17.5 ft. With hypotenuse 28 ft, sin θ = 17.5/28 = 0.625, so θ = arcsin(0.625) ≈ 38.7° ≈ 39°.
