if the length of the shadow of a flagpole 22 ft long is 8.4 ft., determine the angle of elevation of the sun.
What is ?

The angle of elevation ( ) can be calculated by trigonometry.
In this case, Opposite will be the flagpole. Adjacent will be the shadow. Insert the values into the formula and work out .
