In the question it asks about 3 vectors which have magnitudes |A| = 36, |B| = 11, and |C| = 32.5, and θA = 40°, θB = 20°, and θC = 15°.
a) If the magnitude is A+B+C What is the angle between positive x-axis and the vector, measured in clockwise degrees?
b) Use components of magnitude for -A+2B+C, what is gone be the angle between the negative x-axis and this vector measured counterclockwise in degrees?
