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 and the exterior angle are supplementary. That's why you learned about supplementary angles ... or at least they were presented in class ... before polygons.
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
Subtract it from 180
180-interior angle = exterior angle If it's a regular polygon then: 360/number of sides = exterior angle
The interior angle and the exterior angle are supplementary. That's why you learned about supplementary angles ... or at least they were presented in class ... before polygons.
Exterior Angle = 360/number of sides. Interior Angle = 180 - Exterior Angle. Combining Interior Angle = 180 - (360/number of sides).
Each interior angle: 140 degrees Each exterior angle: 40 degrees
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!
360 /each exterior angle
180 minus interior angle = exterior angle because there are 180 degrees on a straight line
Firstly, we have to find exterior angle .To find exterior angle we have to use this formula 360/n (n = number of sides). ex:n=24,you have to do this-->360/24 that is equal to 15.So, the exterior angle of a 24 sized figure is 15o.Now, we have to find interior angle.To find interior angle we have to use this formula 180 -exterior angle.ex:180-15=165.So, dude did you understand and now you dough is cleared .Strike off the dough.
Theorem: An measure of an exterior angle of a triangle is equal to the sum of the measures of the two non-adjacent interior angles.An exterior angle is formed by one side of a triangle and the extension of an adjacent side of the triangle.In the triangle at the right,
