Answer 2

The angle of elevation from the tip of the shadow to the top of the tree is one of the acute angles of the right triangle. The 22-ft shadow is the length of the adjacent side of the angle and 12-ft tree the opposite side. The angle asked for in the problem is the arctan of 12-ft divided by 22-ft. Thus, the angle of elevation is 28.61 degrees.
