Nimfa-mama [501]

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

$tan(A)=\frac{30}{31}$

$A=arctan(\frac{30}{31})=44\°$
