A hill rises from the horizontal at 15º. The road leading straight up the hill is 800 meters long. How much higher is the top of the hill than the base of the hill? Round to the nearest meter. (Enter only the number.)

As usual, draw a figure.
You have the hypotenuse, and the angle.
h/800 = sin 15º = .2588
h = 207m
