Question

A tree 40 feet high casts a shadow 58 feet long. Find the measure of the angle, to the nearest degree, of

elevation of the sun.

Answer 1

39 degrees

Explanation:

Right triangle

40 ft tree = opposite side

50 feet = adjacent side

tan (angle) = opp / adj = 40 /50

arctan (40/50) = 38.66 degrees ~ 39 degrees
