04%) Problem 4: A jet plane flies towards a ground-based radar dish. Radar locates the jet plane at a distance D = 35 km from the dish, at an angle = 59 above horizontal. ©theexpertta.com G> 33% Part (a) What is the jet plane's horizontal distance, DH in meters, from the radar dish?

(to the right and up)Explanation / Answer
(a)
Jet plane's horizontal distance = D * cos(theta) = 35 * cos(59) = 18.026 KM
(b)
Jet plane's vertical distance = D * sin(theta) = 35 * sin(59) = 30.00 KM
(c)
Expression would be = D cos(theta) i + D sin(theta) j
