Work Step by Step

Because of the tick marks, we know that PT=TQ. So, we can set their algebraic values equal to each other. That gives $PT=TQ \rightarrow 7x-24=6x-2 \rightarrow x=22$ The question asks for PT, so we substitute 22 back into the equation of PT, which is $7x-24$. $7(22)-24=154-24=130.$
