11. A skateboard ramp has a slope of 1/2. What is the angle the ramp makes with
the ground to the nearest degree?


Sagot :

we are given with the slope of a ramp that is equal to 2/5, that is x = 5 and y = 2. In this case, we can find the angle of elevation by using the formula: tan Ф = y/x
using a calculator (inverse tangent or arctangent), Ф = 21.8 degrees. In this case, the answer is D. 22 degrees.
