Find the angle of elevation of the sun when a 12.5 meter tall telephone pole casts an 18 meter

long shadow.

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) = 34.78 degrees

The answer would be approximately 34.78 degrees
