The radio station (point A) the point just up the radio station ( point B), and the variable position of the plane ( at specif t point C) shape a right triangle wich hypothenuse L is:

L² = d² + x²

d is the constant distance between the plane and the ground

Then differentiation with respect to time on both sides of the equation

2*L*dL/dt = 2*d* Dd/dt + 2*x*dx/dt

But Dd/dt = 0

L*dL/dt = x*dx/dt

x = 5 miles dx/dt = 570 m/h L = √ d² + x² L √ (5)² + (2)²

L = √29 L = 5.39 m

5.39 *DL/dt = 5*570 m/h

DL/dt = 5*570/5.39 miles/h

DL/dt = 528.76 miles/h

DL/dt = 529 miles/h

Answer:Supplementary angles add up to one hundred eighty (180) degrees, so since you know what angle C is, just subtract that from one hundred eighty (180) and you get one hundred three (103) degrees.
