Solve for x, angle A, and Angle B<br> A x+50 B x+80 c72
jolli1 [7]
I’m assuming you man degrees? Are these angles of a triangle?

This doesn’t really make sense because the angles in a triangle add up to 180° so your equation would be x+50+x+80+72=180

Combine like terms to get
2x+202=180

Then subtract 202 from both sides
2x=-22

So x would be -11 which doesn’t seem right lol
