					                   Two angles may share a certain relationship that will be useful in solving a geometric problem. Determining that a pair of angles is complementary, supplementary, or vertical may be useful in determining other unknown angles.
					                
					                
					             
					                   11x = 4(90-x)
11x = 360-4x
15x = 360
x = 24 degrees
90-x = 66 degrees
