Question

In the sum A+ B =C , vecto rA has a magnitude of 11.0 m and is angled 32.0° counterclockwise from the +x direction, and vector C has a magnitude of 15.0 m and is angled 18.0° counterclockwise from the -x direction. What are the magnitude and the angle (relative to +x) of B?

Answer 1

B = C - A in vector notation. Subtracting a vector is the same as adding its negative. Do the vector subtraction for the answer. Using the components method will get you the x and y components of B. From those two components, get the magnitude and direction
