A gutter at the edge of a roof drops 2 inches for every 30 feet of length. To the nearest tenth of a degree, what is the measure of the angle that the gutter makes with the roof?

Is it 15?
Answered by Steve
the angle is x, where

tan(x) = 2/(30*12)

Where did you get the 12?

You need to convert 30 feet to inches. That's where the 12 comes from.
