It would be 18.49 degrees from the horizontal.
It is the rise over run, which would be 4/12. This equqals 0.3333. To get the angle use the right triangle, and take the arc tangent of 0.3333. This equals 18.49 degrees.

It goes up or down 4 meters for every 12 meters on the horizontal ( in the direction of maximum slope). So it is atan(4/12) from horizontal.

4 inches of vertical rise per foot of horizontal distance. so a right triangle where a squared plus b squared = c squared a=12,b=4 and c=? 144+16=160 so the square root of 160 =c thus c=12.65

it will be 45/3 = 15 degree
12/12 = 45 degree
6/12 = 23.5 degree
4/12 = 15 degree

use tan angle = a/b
4/12
tan angle = 0.3333
arc tan = 18.43º answer
