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.
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
To find the measure of an exterior angle of a triangle, you can use the property that the exterior angle is equal to the sum of the two opposite interior angles. First, identify the exterior angle you want to measure, and then add the measures of the two non-adjacent interior angles. Alternatively, if you know the measure of one interior angle, you can subtract it from 180 degrees to find the exterior angle at that vertex.
the interior angle is about 128.571428 the exterior angle is about 51.4285

180 - interior angle = exterior angle
Subtract it from 180
Exterior angle+interior angle=180 degrees and 180-exterior angle=interior angle
180-interior angle = exterior angle If it's a regular polygon then: 360/number of sides = exterior angle
there is no fix formula for this..........you have to check that what is given to you in the question. According to the given you have to find the interior angle.

Each interior angle: 140 degrees Each exterior angle: 40 degrees
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!
In a regular polygon, the measure of the exterior angle is related to the interior angle by the equation: exterior angle = 180° - interior angle. If the exterior angle is twice the measure of the interior angle, we can set up the equation: exterior angle = 2 × interior angle. Solving this gives us the equation: 180° - interior angle = 2 × interior angle, leading to 180° = 3 × interior angle, or interior angle = 60°. This corresponds to a regular hexagon, as it has interior angles of 120° and exterior angles of 60°.
