For the problem below, draw a diagram representing the problem. In the diagram, label the right angle, given information, and use a variable for the quantity you are being asked to find. Then, set up an equation involving a trigonometric function, that when solved, determines the correct value of your variable. Solve the equation and approximate the value of your answer using a calculator to two decimal places. You can use Desmos (make sure the calculator is in degree mode). State your answer in a complete sentence and include units.
