a hill in the tour de france bike race has a grade of 8%. To the nearest degree, what is the angle that this hill makes with a horizontal line?

An 8% grade means that for everty 100 feet horizontally, the hill rises 8 feet vertically.

So we can use the tangent inverse to find this angle.....we have

tan-1(8/100) = about 4.57°
