the sum of the measures of two exterior angles of a triangle is 225 degrees. what is the measure of the third exterior angle?

OpenStudy (ajprincess):

the sum of the exterior angles of any polygon is 360. so if the measure of the third side is x x+225=360 solve for x. Does that help? @alicekennedy96
