Compute each part of given question:
Question: A vector that is 7.5 units long and a vector that is 5.7 units long are added. Their sum is a vector 9.7 unit long.
Part I: Show graphically at least one way that the vectors can be added. (Do this on paper. Your instructor may ask you to turn in this work.)
Part II: Using your sketch in Part (a), determine the angle between the original two vectors.
I need the exact answer and steps of solving this question. Thanks!
