Given:
Height of stone 3'
Length of shadow 4.5'
Pyth. Ther. 3 sq + 4.5 sq = c sq
c = 5.41
Tan of angle is equal to 4.5 / 3
angle equals 56.3 degrees.
This is the angle of the suns beam in relationship to the 3' tall stone.
The answers of 33.7 degrees is the relationship of the suns beam to the ground.

That is the purpose of school and homework assignments. They want you to figure it out by yourself like we had to do. Learn how to do this and you will not grow up to be a village idiot and on welfare.

opposite = 3 feet
adjacent = 4.5 feet..
after that, simple trigonometry...
