Question

B is the midpoint of AC. If AB= X +5 and BC = 2X -11, find the measure of AB

Answer 1

Hi! Actually, the answer is 21. Because x+5 and 2x-11 are equivalent, set them equal to one another in an equation. Solve for x

You can see my steps in the picture i attached for you!!

Then, once you have x, you need to plug it back in to the expression x+5 (AB) to get 21. I hope this helps you!! :))
