can someone help me with this problem. I mianly want the formula so i can get other questions
its for geometry
okay it's a triangle, and inside the triangle on the left side (A) it says x+1. On the right hand side (B) inside the triangle it says x+15. outside the triangle near the top (C) it says 150 degrees.
it is an exterior angle.
can someone please tell me how i can find all the angles.

OK... first let me say it's been a while since I've done geometry, but if I were trying to solve this problem, I would set the problem up in the following manner:
The angles of a triangle always add up to 180 degrees...
180 = (X + 1) + (X + 15) + X
180 = 3X + 16
180 - 16 = 3X
164 = 3X
164 / 3 = X
so...
X = 54.6667
X + 1 = 55.6667
X + 15 = 69.6667
That is how I would set the problem up.
Good luck!

ok a whole triangle is 180 u have 150 subtract 180-150=30 so on eside is 20 other 10 i think.
