1. A man is standing on top of a 28-foot tall sand pile, and he sees two turtles on the ground below. The turtles are on opposite sides of the sand pile. If the angles of depression from the top of the sand pile to each of the turtles are 25' and 18' respectively, how far apart are the turtles? ( a) Draw a sketch of the situation. b) Use trig functions to solve for the unknown measurements in the sketch. Write out your equations and show all steps of your solutions. Then use the calculator to find the solutions correct to the nearest hundredth of a foot. c) Use the information solved for in part (b) to determine the answer to the question. (Hint: you need to do one additional calculation). d) Answer the question in a sentence.
