A hill that has a 31.4 % grade is one that rises 31.4 m vertically for every 100.0 m of distance in the horizontal direction. At what angle is such a hill inclined above the horizontal?

(1) draw a right triangle.
(2) base = 100.0 m
(3) height = 31.4 m
(4) determine the angle (theta) between the base and the hypothenuse of the triangle.
Use tan theta = opposite side/adjacent side. don't forget to inverse tan. 
How do you find the net force and its direction of the diagrams
