Find angle of elevation from the information below. Thank you.

What is the angle of elevation of the sun when a 65-foot flag pole casts a 28-foot shadow? Round to the nearest tenth of a degree.

Solution

Let the angle of elevation be theta

So, tan(theta) = height/base

= 65/28

= 2.32

tan(theta) = 2.32

theta = tan^-1(2.32) = 66.69 = 66.7 degree
