When the angle of elevation of the sun is 42º, a flagpole casts an 18-meter shadow. How tall is the flagpole, to the nearest hundredth of a meter?
We can use trigonometry for this problem. This would give us:
(tan)42 = x/18
(tan)42*18 = x
16.2 = x.
So the flagpole is around 16.2 meters.
Hope this helped!
