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.
If you mean the ratio of 2,4,6 then the angles are 30 degrees, 60 degrees and 90 degree which in effect is a right angle triangle.
In a parallelogram adjacent angles are supplementary, so angles are 75 degrees (A & C) and 105 degrees (B & D).
30 degree angle
Complementary angles add up to one right angle (90 degrees), such as 30 degrees and 60 degrees. Supplementary angles add up to a straight angle, which is 2 right angles (180 degrees). So the supplement of a 30 degree angle is 150 degrees. For any given angle, its supplement is 90 degrees greater than its complement.
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.
180 - 30
If you mean the ratio of 2,4,6 then the angles are 30 degrees, 60 degrees and 90 degree which in effect is a right angle triangle.
a 60-degree angle
A 60 degree angle
Complementary angles add up to 90 degrees. So, 90 - 30 = 60. The complement of 30 degrees is 60 degrees. Supplementary angles have a sum (add up to) 180 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.
It is 60 degrees
A pair of supplementary angles adds up to 180 degrees. Therefore, the supplement to a 150 degree angle is 180 - 150 = 30 degrees.
In a parallelogram adjacent angles are supplementary, so angles are 75 degrees (A & C) and 105 degrees (B & D).
