Aramp goes from a doorway of a building to the ground. the end of the ramp connected to the doorway is 1 foot above the ground. the distance along the ramp to the building is 5 feet. what is the angle of elevation of the ramp to the nearest degree?

11,3º above the horizontal.

Step-by-step explanation:

In order to sove this you just have to calculate with the laws of sine, you are creating a rigth triangle, and you know the opposite side and the adjacent side to the angle, which is 1 foot the opposite and 5 feet the adjacent, the function that uses those two is Tan, so tan = Opposite/adjacent

Angle=Tan-1=1/5

Angle: Tan-1*,2

Angle=11,3

So the angle that is formed by the ground and the ramp will be 11,3 grades above the horizontal.
