I do believe that the 3 vertices form a right triangle. I mean it uses perpendicular lines to see if you can form a right triangle with vertices. I really do hope I helped ^^
First:
Subtract 5 on each side of the equals sign to cancel it out. You should get 13x=144.
Next:
Divide 13 from each side of the equals sign to get x by itself.
Answer:
X=11.0769230769. You may need to round it up to 11.08 or 11.1 depending on how your teacher normally has you answer
