If a building casts a shadow 150 feet from its base, and a yardstick casts a shadow of 2 feet, how tall is the building? use trigonometric functions to solve the problem.

To measure the elevation of the sun, we have to divide the y by x. which is 50 divided by 68. We get the angle of elevation as 73.53 degrees. The height of the building is our y and the shadow of the building is our x in this problem. Divide them to get the angle of elevation.
