The airplane is 500 m directly above P, A is the position of the airport, x is the x component of the position vector of the airplane and y is its y component. The horizontal distance AP is 15 km or 15000 m. What trig function relates the distance from B to A , the distance from A to P and the measure of the angle BAP? What trig function relates the distance from B toP, the distance from A to P and the measure of the angle BAP? Solve for x and y. Penny
