To answer this problem, you should know the formula that we will be using and this would be:
Angle of elevation = arc tan( (vertical height)/(length of the shadow)).
Plugging in the values in the formula. Here, this angle is:
arc tan (12.5/18) = <span>34.78 degrees</span>
The answer would be approximately 34.78 degrees
16 divided by 14, 1/7 times 8, and 16/14 goes under 8/7. 14/16, 1/16 times 14, 7 divided by 8 go under 7/8

Hope you could get an idea from here.
