If a road has a 10 degree incline, what is the percent grade of the road?

Step 1 ：First, we need to understand the conversion from degrees to percent grade. The tangent of the degree of the incline is equal to the percent grade. So, we need to find the tangent of 10 degrees.

Step 2 ：In the calculator, we input 'tan(10)' and we get 0.1763

Step 3 ：This value is the decimal equivalent of the percent grade. To convert it to percent, we multiply by 100.

Step 4 ：So, the percent grade is 0.1763*100 which is 17.63
