+290 From point P on the ground, the angle of elevation of an airplane is 23º. The altitude of the plane is 1200 meters. What is the distance from point P to the airplane, to the nearest tenth of a meter?
+37147 d = hypotenuse of the right triangle = distance to the plane from point P
sin 23 = 1200 / d
d = 1200 / sin 23 =~ 3071.2 m
