Question

The measurement of an angle is 34 what is the measure of its supplement

Answer 1

the measure of its supplement would be 146 degrees.

supplementary means that two angles add up to 180 degrees, aka form a straight line, so to get the answer for this i simply subtracted 34 from 180.

Answer 2

the supplement of the angle would be 146 or 56 depending if the main angle of the two is a supplementary angle or complementary angle...
Supplementary-180-34=146
Complementary-90-43=56

Hope this helped
