**Anonymous**, Thursday, September 29, 2011 at 4:50pmYou're going to use sin = 0pposite / Hypotenuse.

In this case the hypotenuse is 325 mph, the opposite side is the gain in altitude, 20 degrees is your angle.

Therefore sin 20 = Opposite / 325 mph

sin 20 * 325 = Opposite

111.15 mph = opposite

The airplane is climbing at a rate of 111.15 mph
