Suppose that angle COP and angle TOD are vertical angles, the measure of angle COP is 11x-17 and The measure of angle TOD is 9x+11. Part A: construct angle COP and angle TOD [Hint: angle COD is an adjacent angle to angle COP and angle POT is an adjacent angle to angle TOD.]

Part B: determine the measure of angle COD and the measure of angle POT.
