Answer:

14.04°

Explanation:

In this right triangle, we're seeking the measurement of an angle at the base of the triangle and we have the measurements of two of the sides (none are the hypotenuse) : the opposite one of the angle and the adjacent side.

The relationship between the two sides we have the measurement and the angle we are looking for is the tangent:


tan(\alpha) = (a)/(b) = (5)/(20) = 0.25

To find the angle we do an arctan on 0.25 and we get an angle of 14.04 degrees.
