Answer:
Option C. 44 degree
Step-by-step explanation:
Let
A-----> the angle of the elevation of the sun
we know that
The tangent of angle A is equal to divide the opposite side angle A by the adjacent side angle A
In this problem
The opposite side is 30 meters
The adjacent side is 31 meters
[tex]tan(A)=\frac{30}{31}[/tex]
[tex]A=arctan(\frac{30}{31})=44\°[/tex]
