proving Mn and Ac parallel

You're missing a piece of information. Perhaps they told you that angle A is a right angle?

Ah, you didn't say that BC = 10. That's what I wanted.

#

This is doing to be an argument about similar triangles.

I angle A probably a right angle since the dimensions are a Pythagorean triple

#

Know you can find the other angle using tig

#

more important, you can find angle b which is part of triangle BMN.

You don't need to find any angles. There's no trig in this question. It is a right triangle, but it doesn't matter that it is.

my approach to the proof.

#

Thales theorem is based on congruent angles so.....

#

Congruent angles is what you're trying to prove

yes
