Part B Based on your answer from part A, you should be able to find the lengths of the sides of a 30°-60-90° triangle given the length
of any side. Use this information to find the height of the building described in the following scenario.
A building casts a 15-foot shadow on the ground. A person standing at the end of the shadow can view the top of the building
at a 60° angle with respect to the ground. Set up a proportion based on the similar triangles in this situation and the given
special triangle. Show the proportion, and solve it to determine the exact height of the building.
