Question

Asked Nov 7, 2019

A man 5 ft 9 in tall stands on a sidewalk that slopes down at a constant angle. A vertical street lamp directly behind him causes his shadow to be 25 ft long. The angle of depression from the top of the man to the tip of his shadow is 31^{o} . Find the angle (alpha) that the sidewalk makes with the horizontal.

Step 1

Given that
