A 9.5-foot pole casts a shadow that is 29 feet long. What is the approximate measure of angle L?

This is the concept of application of trigonometry, to get the value of the angles of elevation we use the formula:

tan theta=opposite/adjacent

opposite=9.5 ft

adjacent=29 ft

tan theta=9.5/29

thus:

theta=tan^ (9.5/29)

=18.14

therefore the angle of elevation will be:

angle L=18.14
