X = 180 - Y so 180 - Y = 2x + 4 and Y = 4x + 20 so 180 - 4x - 20 = 2x + 4
therefore 6x = 156 so x = 26 making Angle X = 56o and Angle Y = 124o
The sum of two supplementary angle equals 180 degrees.

Supplementary angles are angles that add up to 180 degrees, ie. a straight angle. Therefore, the angle supplementary to 101 degrees would be 180-101=79 degrees.
Supplementary angles are angles whose sums =180 degrees. You have a 65 degree angle + it's supplementary angle = 180 degrees. So, to find the supplementary angle, subtract 65 from 180. 180 - 65 = supplementary angle. 115 = supplementary angle. To check, add the angles together. 65 + 115 = 180 (check) (Also, you might be working with complimentary angles. Complimentary angles are angles whose sum = 90 degrees.)
The angles are supplementary if they have a sum of 180 degrees.
Two angles are complementary if their sum equals exactly 90 degrees. Two angles are supplementary if their sum equals exactly 180 degrees, so a 30 degree angle is supplementary with a 150 degree angle.
Supplementary angles are two angles that measure up to 180 degrees. EXAMPLE: If the an angle measures 70 degrees, to find the missing angle, you subtract 70 from 180 because supplementary angles equal 180 degrees. Your answer (in this case 110) is the answer for the measure of the missing angle.
The sum of two supplementary angle equals 180 degrees.

An angle and the angle that it is supplementary to have a total measure of 180 degrees.Let x be the supplementary angle. 4x would be the original angle.x + 4x = 1805x = 180x = 364x = 144So the two angles are 144 degrees and 36 degrees.
Supplementary angles are angles that add up to 180 degrees, ie. a straight angle. Therefore, the angle supplementary to 101 degrees would be 180-101=79 degrees.
Its supplementary angle is 160 degrees because supplementary angles add up to 180 degrees
Supplementary angles add up to 180 degrees so it is 100 degrees
Two supplementary angles add up to 180 degrees.
120 Since the measures of the angles of supplementary angles add up to 180, 60 plus something else equals 180. 180-60=120
