Answer:

BC = q +p

Step-by-step explanation:

Here's one way to get there. Two vector sums are the same if they have the same starting and ending points. The sum AC can be expressed two ways:

AB +BC = AD +DC

p +BC = q +2p . . . . . . using givens, and your result from part (a)

Subtract p from both sides:

BC = q +p
