The measure of an exterior angle of a triangle is 75 degrees. If one of the non-adjacent interior angles measures 28 degrees, what is the number of degrees in the other non-adjacent interior angle?

We can use the Exterior Angle Theorem to  solve this

 

75  = 28  +  x       subtract 28 from both sides

 

47°   = x   =  the measure of the other  non-adjacent  interior  angle
