Best ResponseYou've already chosen the best response.0well 55 plus 45 = 100 so 180 minus 100 equal 80.

Best ResponseYou've already chosen the best response.0sum of interior angles in a triangle, as @DisCrazyGinger said, is 180 so.. notice the "given" angles already, all that's missing is "y", if one is 45 and the other 55, what is "y" for the sum to be 180?
