Oh, dude, the supplement of an angle is just 180 degrees minus the angle itself. So, for a 140 degree angle, the supplement would be 40 degrees. It's like when you order a Pizza and you know exactly how many slices are left for you to devour.
Angle is x degrees. Then 2(180 - x) = 5(90 - x) + 30 360 - 2x = 450 - 5x + 30 3x = 120 x = 40 Check: supplement is 140, 2 x 140 = 280 complement is 50, 5 x 50 = 250 difference is 30 as required. QED

Since the interior angle measure of the regular polygon is 140⁰, its exterior angle measure is 180⁰ - 140⁰ = 40⁰. Since the sum of the exterior angle measures is 360⁰, the polygon has 360⁰/40⁰ = 9 sides.

You would subtract 40 degrees from 180 degrees so it would look like this:180 degrees - 40 degrees = 140 degrees
40-degrees 140-degrees
A 140 degree angle is about half way between a 90 degree angle, which has lines that are perpendicular to each other, and a 180 degree angle, which is a straight line. A 140 degree angle is an obtuse angle which has a line a little over half way between the 90 degree and 180 degree angles.
A 140 degree angle would be called an obtuse angle.

No angle can be complementary to a 140 degree angle, as the sum of complementary angles is 90 degrees. But angles which are supplementary to each other add together to form a 180 degree angle.

Angle is x degrees. Then 2(180 - x) = 5(90 - x) + 30 360 - 2x = 450 - 5x + 30 3x = 120 x = 40 Check: supplement is 140, 2 x 140 = 280 complement is 50, 5 x 50 = 250 difference is 30 as required. QED

The sum of the angles is 180 degrees in any triangle. So 180-140 is 40 and the third angle is 40 degrees.
