LekaFEV [45]

Answer:

C.) 53°

Step-by-step explanation:

We have a right triangle with base of 25  (the distance apart) and (45-12 = 33) for the height.  We want to find the angle of elevation.

tan angle = opposite side/ adjacent side

tan angle = 33/25

Take the inverse tan of each side

tan ^-1 (tan angle) = tan ^ -1 (33/25)

angle = 52.8533133

Rounding to the nearest degree

angle = 53 degrees
