No, you cannot find the exterior angle before the interior because the interior angles can vary in many ways.
180 - interior angle = exterior angle
Subtract it from 180
the interior angle is about 128.571428 the exterior angle is about 51.4285
40 degress because a straight line is 180 degrees and an interior angle with its exterioir angle is a line spilt in half so to find the interior/exterior angle, taek 180 and subtract the interior/ exterior angle and then you will get the the other angle, sorry this is kinda conufsing!

180 - interior angle = exterior angle
Exterior angle+interior angle=180 degrees and 180-exterior angle=interior angle
Subtract it from 180
180-interior angle = exterior angle If it's a regular polygon then: 360/number of sides = exterior angle
Exterior Angle = 360/number of sides. Interior Angle = 180 - Exterior Angle. Combining Interior Angle = 180 - (360/number of sides).
the interior angle is about 128.571428 the exterior angle is about 51.4285
Each interior angle: 140 degrees Each exterior angle: 40 degrees

360 /each exterior angle
It is: 180-interior angle = exterior angle
It is: 180-interior angle = exterior angle
