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](https://img.qammunity.org/2020/formulas/mathematics/high-school/x9oh58azdartnt87m39ciajjqim9con66c.png)
To find the angle we do an arctan on 0.25 and we get an angle of 14.04 degrees.
