To the nearest degree, what angle does a hill with a grade of 11% make with a horizontal line?

Tangent= Opposite/Hypotenuse Tan 9/15=30.96 (This is the Smallest Angle) Check: 90(This is the Right angle)+30.96=120.9 180-120.9=59.1(This is the third angle.) 9/sin 30.96 = 15/sin 59.1. This Does Work. So the Smallest Angle is 30.9 Degrees, rounded to 31.

The point on the curve for y = sqrt(2x+1) at which tangent is perpendicular to the line y = -3x + 6 is.... a. (4, 3) b. (0,1) c. (1, sqrt3) d. (4, -3) e. (2, sqrt 5) I'm not sure, but do you find the perpendicular slope (1/3) set that as dy/dx and solve for x or y? I tried...
