Road drop

On a straight stretch of road is marked 12 percent drop. What angle makes the direction of the road with the horizontal plane?

Result

x =  6.843 °

Solution:

x=180πarctan(12/100)6.8428=6.843=65034"x = \dfrac{ 180^\circ }{ \pi } \cdot \arctan(12/100) \doteq 6.8428 = 6.843 ^\circ = 6^\circ 50'34"
