120 degrees.
When will degree supplementary exams start?
Two angles put together to create a 180 degree angle.Supplementary angles add up to 180 degrees as for example the supplementary angle of 120 degrees is 60 degrees because 120+60 = 180 degrees.
Since the sum of measures of the two supplementary angles is 180⁰, we have:180⁰ - 165⁰12' = 179⁰60' - 165⁰12' = (179 - 165)⁰(60 - 12)' = 14⁰48'
It is 120-degree angle are supplementary.
Its supplementary angle is 121 degrees
180 degrees
answer
120
60 because supplementary angles add up to 180
