Brian wants to build a ramp that leads to a 5 meters above the ground. He wants the ramp to be 10 meters long. What should the angle of elevation of the ramp be

Question

I cant figure out this problem, and  I was looking for some help

Answer 1

I believe that you are describing the following triangle (side view of ramp):

 

horizontal leg; vertical leg 5 m above ground (horizontal leg); hypotenuse 10 (ramp length).

 

Right away, you should recognize this right triangle because it has one leg = half of the hypotenuse; therefore the angle of elevation is 30 degrees.
