there is a picture attached above @roberman228

It is an equilateral triangle. What can you say about the two other angles of the triangle?
anonymous
  • anonymous
x=45
ZeHanz
  • ZeHanz
No, could you answer my question, please?
anonymous
  • anonymous
What?
anonymous
  • anonymous
that they are equal, so x equals 45?
anonymous
  • anonymous
zehan mention me in your ? and i'll come to it
anonymous
  • anonymous
wait no, cause x is equall to the opposite inner angles? so x = 80?
ZeHanz
  • ZeHanz
Both angles in the triangle are equal. Sum of all angles in a triangle is how many degrees?
anonymous
  • anonymous
exactly, x=80
anonymous
  • anonymous
180. @ZeHanz
ZeHanz
  • ZeHanz
@Foreverisabell: so what is left for the two equal angles?
anonymous
  • anonymous
Im still confused.
anonymous
  • anonymous
all the angles have to equal 180 inside no?
ZeHanz
  • ZeHanz
Sum of angles is 180. One angle is 40. Sum of other two angles is 140. The other two angles are equal, so 70 degrees each.
anonymous
  • anonymous
Oh alright thank you.
anonymous
  • anonymous
So that means x = 70 + 40?
ZeHanz
  • ZeHanz
Yes! See, it is not that hard...
anonymous
  • anonymous
can you help me with one more thing?
anonymous

ZeHanz
  • ZeHanz
Sure!

I can see it ;) If P is a centroid, then P divides QT into two pieces, QP and PT, with QP:PT =2:1 Now you know the length of QP (=14), so what would be the length of PT?
anonymous
  • anonymous
14 + 14? zoo. 28?
anonymous
  • anonymous
*sooo
ZeHanz
  • ZeHanz
No, QP:PT=2:1, so QP is double the length of PT, so PT would be 7. So total 14+7=21
anonymous
  • anonymous
oh okay now I get it.
