Brenda finds that the angle of elevation of the top of the flagpole 145 ft. from the foot of the pole 38�25'. What is the height of the pole?
-----
Draw the picture.
You have a right triangle with height = "h", base = 145,
and base angle = 38 25' = 38.42 degrees
======
Equation:
tan(38.42) = h/145
----
h = 145*tan(38.42) = 115 ft.
