Answer» I assume you mean the EXTERIOR ANGLE is 4x. Draw a polygon, any number of sides. NOW, extend one side, on the angle of interest Note how when you extend that side, you get a straight line. O.K., now how many degrees are there in a straight line??? Label the interior angle 2x, and the exterior angle 4x. Together, they add up to 6x, and must equal the number of degrees in a straight line. SO: 2x + 4x = 180 |
