A driveway has an incline of 3m over a distance of 20m What is the angle of elevation of the driveway?
:
This forms a right triangle, the angle (A) formed by the base and the hypotenuse is the angle of elevation: Use the tangent: Side opposite = 3, side adjacent = 20
:
Tan(A) = 3%2F20
:
Tan(A)= .15
:
Find Arctan of .15
:
A = 8.53 degrees
