Consider the diagram shown where a tree that is 100 ft tall casts a shadow 120 ft long. Find the angle of elevation of the sun. (to the nearest degree)

Our given is 100 ft and 120 ft.

So based on the problem gives us a right triangle with a height 100 feet and a base of 120 feet.

To solve this, the formula to be used is:

Angle = tan^-1 (h/b)

= tan ^ - 1 (100 / 120)

= tan ^ - 1 (0.8333333)

= 39.81 degrees is the angle of elevation
