A set of stairs has a vertical rise of 16 cm for every 27 cm horizontal run. What is the angle, to the nearest tenth of a degree, between the stairs and the floor?

The tangent of the angle is given by rise/run, so calcuate tan-1(rise/run)

 

Since you want the answer in degrees, make sure the calculator you use is in degree mode (or else convert after if it's in radian mode).
