Question 613725: A ramp that is 18 meters long makes an angle of 9º with the ground. What is the height h of the ramp? Round your answer to the nearest tenth of a meter.
Answer by jim_thompson5910(35256) (Show Source): You can put this solution on YOUR website!
sin(theta) = opposite/hypotenuse
sin(9) = h/18
18*sin(9) = h
h = 18*sin(9)
h = 18*0.156434465040231
h = 2.81582037072416
So the height of the ramp is roughly 2.81582037072416 m which rounds to 2.8 meters
