Thanks! :) I thought it made sense to make it into a quadratic equation. Stupid me... I didn't factorise correctly.

I used the arctan key of my hand calculator. If you don't have one, you should use a table of trig functions

The answer to your second question is the tangent of 8 degrees. That is 0.1405, for a 14.05% grade. You don't find many roads that steep. Driveways, maybe.

sorry one more question. so... a road climbs at an 8 degree angle with the horizontal. what is the grade of the road? the answer would be 5?

The "grade" is the tangent of the slope angle. arctan 0.07 = 4.00 degrees (4 degrees is the angle whose tangent is 0.07)

let one leg be x then the other leg is 80 - 34 - x = 46-x x^2 + (46-x)^2 = 34^2 x^2 + 2116 - 92x + x^2 = 1156 2x^2 - 92x + 960 = 0 x^2 - 46x + 480 = 0 (x -30)(x-16) = 0 x = 30 or x = 16 if x=30, other leg is 46-30 = 16 if x = 16 , then other leg is 46-16 = 30 (symmetrical ...
