The two vectors a and b have equal magnitudes(on an x-y plane vector a is 30 degrees from the x axis then vector b is 75 degrees from the head of vector a it is heading towards north west) of 10m
A)find the x component of their vector sum r
B)find the y component of their vector sum r
C)The magnitude of r
D) the angle r makes with the positive diretion of the x axis.

Can you help me? I don;t get how you get these answers
Your description of directions begs for amplification. I recommend you change both vectors to x,y coordinates.
