Question

Use the figure to the right to find the value of PT

Answer 1

the figure show, the length between P and T and the length between T and Q, are equal.

so we can say PT=TQ

PT= 3x+2 and TQ=5x-6

so we can replace:

3x+2=5x-6

now we solve

2+6=5x-3x

8=2x

8/2=x=4

and finally, to find PT we replace x by 4

PT=3*4+2=14

So the answer is: PT=14
