Question

in the given figure ......

Answer 1

It will be equal to 85°
Right now I couldn't post the pic of solution but here's a way to solve it

First draw any ray through point M and give it any name suppose AB such that it is parallel to both PQ and RS

Now PQ // AB
Therefore angle XMB = 180-135
= 45°

Next AB is parallel to RS
Therefore angle YMB = 40°

Now angle M = 40+45
= 85°

Hope this is helpful:)
