Final answer:
To find the measure of PT and PR when QT is the perpendicular bisector of PR, we can use the given information and equations to find the measure of PQ and QR. However, to find the measure of PT and PR, we need additional information.
Step-by-step explanation:
To find the measure of PT and PR, we need to use the given information. We are told that QT is the perpendicular bisector of PR, which means it cuts PR into two equal halves at T.
Since QT is the perpendicular bisector, PQ and QR will be equal. PQ is given as 4x + 4, so substituting y for PQ, we have y = 4x + 4. Similarly, QR is also given as 4x + 4, so substituting y for QR, we have y = 4x + 4.
To find the measure of PT or PR, we need more information.
