Let triangle PQR be as shown. Do NOT assume this is a right triangle (it isn't). P R Q → Which of the following expresses QR in terms of PR and PQ? OPQ-PR OPR + PQ PR- All of these Use the law of cosines to find the measure of ZQPR in terms of PR and PQ. You may use the theorem that ||v||2 = = v. v and the distributivity of the dot product (u+v) wu w+v w. You may NOT use any other property of the dot product.
