Cisco is 50 feet from the base of the tree when he spots his friends zorro the cat at the top of the tree that is 42 feet high,
Dmitry_Shevchenko [17]
Given both the distance from the tree and the height of the tree, the angle of elevation can be obtained using the tangent formula, tangent theta = opposite side / adjacent side. In this case, opposite side = the tree's height and the adjacent side is the distance of Cisco to the tree. Therefore, the angle of elevation equals 40.03 degrees.
