Which of the vectors π, π, π, π, and π shown in the diagram is equal to π¨ plus π©?

The diagram weβre given is this set of Cartesian axes with several vectors all represented as arrows. The vector π¨ is represented by this arrow. The vector π© is represented by this arrow. And our task is to identify which of the other vectors is equal to π¨ plus π©. So letβs recall how to add two vectors when they are represented by arrows. An arrow representing a vector has a head, thatβs the pointy end, a tail, thatβs the other end. And a straight line connects the tail to the head. Now, when we want to add two vectors, we draw the tail of one vector at the head of the other vector. If we connect the other tail to the other head with a straight line, this new vector is exactly equal to the sum of the two vectors we had previously drawn.
