Jamison takes a 20 foot board and props it up with a one foot block at the far end to make a daredevil jump ramp for his bike. What is the measure of the angle of elevation of the ramp to the nearest degree?
The 20 foot board will be the hypotenuse of a right triangle formed by the board, the road, and the 1 foot block.
The angle of elevation will be the angle formed where the board meets the highway.
You have opposite side and hypotenue. Use inverse sine to find the angle of elevation.
