A construction crew is placing a support beam against the side of a building to ensure that the building remains at a 90° angle to the ground. The beam will be fixed to the ground 15 feet away from the building at a 38° angle, as shown. Complete the equations to show two ways to solve for x, the length of the support beam. 38 15 feet 15 38° = 15 sin
