And what exactly were you asked to do with that?

given that \(m\angle Q=42^{\circ}\), and the line NQ bisects \(\angle MNP\), and the line PQ bisects \(\angle MPR\) Find \(m\angle M\)

not sure if it's the notation that is throwing me off?

the internal angle sum of a triangle is 180° the internal angle sum of a quadrilateral is 360°

are the lines QM and RN parallel by any chance?

  • richyw
I wasn't sure, but I tried under that assumption.

  • richyw
oh the answer is 84 by the way. This isn't what I got

  • richyw
yup just tried again. is anyone actually trying this?

i dont think those lines could be parallel
richyw
  • richyw
that is what I figured as well. so I attempted by just assuming that N,P and R all lie on one line. But then I can't figure out if there is a solution.

I have to give up! If someone figures it out please post it. I really don't know.

The question seems to be missing something. Is there a length somewhere? Or maybe it's cylic? It's brings me to a wild goose chase....
anonymous
  • anonymous
What's the answer? 84? if it's 84 then its parallel...
richyw
  • richyw
how did you work that out?

@Shadowy, your logic appears to be flawed: 2(42) + 2x = 180? How?
anonymous
  • anonymous
Well,since \(\Delta \)MPN is an isosceles triangle, angle MPN=angle MNP, so at the point P, y=42, 2y+2x=180.
Hero
  • Hero
Bro, there's no evidence that suggests MPN is isosceles

If and only if the MQ and NP is parallel, then as shown above, QM=MP=MN. And the answer happens to be 84. So this assumption is right.
