A ramp used to load vehicles on to a truck is 15 feet long.  The ramp makes a 35 degree angle with the ground.  Find how high the upper end of the ramp is above the ground

We can use the sine here


sin 35  = h / 15      where h is the ramp height


Multiply both sides  by 15


15 * sin 35  = h  ≈  8.6 ft
