For vectors B = -2î – 8j and A = -6î – 4j, calculate the following. (a) Á + B (Express your answer in vector form.) A + B = -8i – 12j Enter the magnitude and direction (in degrees counterclockwise from the +x-axis) for A + B. magnitude 14.42 direction 56 ° counterclockwise from the +x-axis (b) Á - B (Express your answer in vector form.) A - B = -4i + 4j Enter the magnitude and direction (in degrees counterclockwise from the +x-axis) for A – B. magnitude 5.66 direction -45 ° counterclockwise from the +x-axis
