@bill533 what mean angle bisector ? what make segment MB with angle AMC ?

Answer 3

Easy. Bisector means that the angle is split into 2 different, but equal angles. So in order to solve for x, simply just set both equations equal to each other. x+25=3x+5. Do some meth here and there, and you'll find x = 10.
