Question

The supplement of a 25°angle is an angle with a measure of

A.65°
B.155°
C.75°
D.55°

Answer 1

The answer is B ( I think) because if one angle measure is 25° and it's a supplementary angle (EQUAL TO 180) then it's other measure will be 155°.

Answer 2

supplementary angles, when added, will equal 180 degrees

so if one angle is 25, then its supplementary angle = (180 - 25) = 155
