Answer 1

Problem 2: A plane flies towards a ground-based radar dish. Radar locates the plane at a distance D = 29 km from the dish, at an angle θ = 44° above horizontal.

Randomized Variables
θ = 44 degrees
D = 29 km

Write an expression for the distance vector, D, in rectangular form in terms of D, θ and the unit vectors i and j.
D =
