Question

what is vector C in this case? 

y 11.5 23.9 72.1° 18.9 There are two vectors shown in the previous figure. The red vector, vector A, has a magnitude of 11.5 and makes a 23.9° angle with +x. The other purple vector, vector B, has a magnitude of 18.9 and makes a 72.1° angle with-x. Determine the sum of the two vectors (A+B) by indicating its magnitude and direction. Problem 2 Determine the vector C, such that when it is added to vector A (the red vector in the previous figure), the resultant vector only has a negative y component and its magnitude is 10.
