The ramp for the start of the flying fox is 3 meters long and forms an angle of 78 with the ground. Find the height between the top of the flying fox and the ground

If I understand correctly, the ramp looks like this:

sin( angle ) = opposite / hypotenuse

sin( 78° ) = height / 3 , where height is in meters.

3 sin( 78° ) = height

height ≈ 2.934
