8 REAL WORLD LAW OF SINES OR COSINES A commuter plane flies above the Delaware River. There is a boat at point A and a swimmer 3 miles away from it, at point B. When the plane reaches point C, the angle of elevation from the boat is 43 o, while the angle of elevation from the swimmer is 67 o. Determine how many miles above sea level the plane is at point C. *FIGURE NOT DRAWN TO SCALE*

9 Calculate the area of the quadrilateral.
