Hi,

I've been puzzling over this problem.

I think the answer isVector A lies in the first quadrant, whereas vector B in the second quadrant. Neither vector is parallel to the x-axis. What can be said with certainty about their sum C = A + B? Choose all answers that apply.

C lies in the first quadrant.

Its component Cx is positive.

Its component Cy is positive.

Its length C is nonzero.

Because you're adding two vectors that are in quadrants I and II, then the y component of the new vector should be positive. Is this correct?Its component Cy is positive.
