Question

a plane is located on radar by an air traffic controller. what are the magnitude and the direction angle of the vector from the airport to the plane?

Answer 1

C The magnitude is 7.94, and the direction angle is N 49.91° E.

magnitude formula: sqrt x^2+y^2

sqrt 6^2+5.2^2

7.94

direction angle: tan^-1(x/y)

tan^-1(6/5.2)

49.91 (convert radians to degrees)
