Question 734877
We use some trig here to get the angle of the spotlight with the ground

note that we are given a right triangle with 25' for the side represented by the flag pole and 20' for the side represented by the distance from the flag pole where the spotlight is located......so

the tangent of the angle for the spotlight is 25/20 or 1.25 and

the angle whose tangent is 1.25 is 51 degrees which is the answer
