A plane flies towards a ground-based radar dish. Radar locates the plane at a distance D = 32 km from the dish, at an angle θ = 31° above horizontal. Part (a) What is the jet's horizontal distance, DH in meters, from the radar dish? DH 11114.5 DH = 1 1 110 V Correct! 33% Part (b) What is the jet's vertical distance, Dv in meters, above the radar dish?
