Suppose the angle is x
then its supplement is 180 - x
so 180 - x = x - 78
that is, 258 = 2x or x = 258/2 = 129
<><><><><>
Angle + Supplement = 180
Angle = Supplement + 78
Solve for the system of equations...
Angle + Supplement = 180
Angle - Supplement = 78

2 Angle = 258
Angle = 129
Supplement = 51
Two supplement angles add up to 180⁰. So we have:x + (x - 36) = 1802x = 180 + 362x = 216x = 216/2x = 108Thus, the angles are 72⁰ and 108⁰.

The angle is 160 degrees and it's supplement is 20 degrees.
A supplemental angle "completes" a given angle to make it a straight angle (180 degrees). The supplement of 90 is 90. The supplement of 100 is 80. As long as the two angles add up to 180 they supplement each other. So, you have some angle, x and its supplement, 180-x. The supplement is twice as big as the angle. 180-x = 2*x Solve for x and you're done!
60 degrees and 120 degrees
Two supplement angles add up to 180⁰. So we have:x + (x - 36) = 1802x = 180 + 362x = 216x = 216/2x = 108Thus, the angles are 72⁰ and 108⁰.
A pair of supplementary angles add up to 180 degrees. In this instance, the supplement of an angle of 70 degrees is 180 - 70 = 110 degrees.
The sum of supplementary angles is 180° . The supplementary angle of 93° is 180 - 93 = 87°

The angles are: 75 degrees and 105 degrees
ComplementComplementary angles sum to 90o, thus: The complementary angle of 45o is 90o - 45o = 45oSupplementSupplementary angles sum to 180o, thus: The supplementary angle of 45o is 180o - 45o = 135o
130 and 50 degrees.
180 - 31 = 149o
108 degrees
Two angles are said to be supplementary if they total 180 degrees. To find an angle's supplement, subtract its measure from 180.
The angle is 160 degrees and it's supplement is 20 degrees.
