13x-28=6x+7 because of the circumcenter theorem. You can solve for x
When you find x, you can plug c back into you equation for line segment NE
Knowing what NE is, you also know what ME is because of the circumcenter theorem. When you find ME, you can use the Pythagorean theorem. ME is the hypotenuse, DE is A. Solve for B to find segment MD.
I hope this helps even though I didn’t solve anything. For studying/doing problems you don’t understand, I would recommend thinking about how you would solve the problem first, and then solve the problem. Please give brainliest!
