Suppose the angle is x, Then its supplementary is 180-x

So x+39 = 2(180-x) = 360-2x

Then 3x = 399

So x = 133 and 180-x = 47

Supplementary angles add up to 180 degrees. If one angle = 130 degrees the other must be 180 - 130 = 50 degrees

No, an obtuse angle cannot be both complementary and supplementary because the measures of complementary angles add up to 90 degrees, while the measures of supplementary angles add up to 180 degrees. An obtuse angle has a measure greater than 90 degrees, so it can only be supplementary, not complementary.

Straight line, or 2 angles that add up to 180 degrees are called supplementary angles.

a straight line or supplementary angles...which equal to 180 degrees.

Angles on a straight line add that up to 180 degrees are called supplementary angles

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.

If two angles are supplementary, and one angle measures 30 degrees, then the second angle must measure 150 degrees. This is because by definition if two angles are supplementary, then they must up to 180 degrees.

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.

Supplementary angles add up to 180 degrees. If one angle = 130 degrees the other must be 180 - 130 = 50 degrees

Two adjacent angles are considered supplementary angles. They aggregate and make an angle that measures 180 degrees.

No, an obtuse angle cannot be both complementary and supplementary because the measures of complementary angles add up to 90 degrees, while the measures of supplementary angles add up to 180 degrees. An obtuse angle has a measure greater than 90 degrees, so it can only be supplementary, not complementary.

Straight line, or 2 angles that add up to 180 degrees are called supplementary angles.

When 2 or more angles add up to 180 degrees they are said to be supplementary. Supplementary angles only occur on straight lines, so if one angle is said to be 120 the other angle has to be 60 degrees in order to form a straight line and also to add the angles to 180 degrees

Supplementary angles add up to 180 degrees and angles on a straight line add up to 180 degrees
