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
