<PRE><B>Question 437753</B>
A 25-foot steel beam is leaning against a wall. The bottom of the beam is 15 feet from the wall. What is the size of the angle that the beam makes with the ground? Round your answer to the nearest degree. 

--------------------
Draw the picture. You have the hypotenuse
and you have the side adjacent to the angle.

cos^-1(15/25) = 53.13 degrees
