Question

A 15 ft tree casts a 9 foot shadow on the ground. What is the angle of elevation formed by the tree’s shadow and the sun? (Round to the nearest hundredth)

Answer 1

59.04

Explanation:

If you were to make a right triangle, 15 would be the altitude (height), and 9 would be the base. You need the angle of elevation which is going the angle of the hypotenuse going upwards. (Bottom Left/Right Corner.) From that angle you need to solve for arctan (Used for solving the measure of angle.) Simply plug into your calculator arctan(15/9) to get the answer.
