Question

Points Possible: 1, Points Correct: 0 ∠A and ∠B are supplementary. If m∠A = 83° , what is the measure of ∠B?

Answer 1

97? not an option. Maby 98

Answer 2

So the definition of a supplementary angle is two angles that add up to 180 degrees
The problem you gave already gave angle A which is 83 degrees, therefore all you have to do is take 83 degrees and subtract it from 180 degrees which equals to 97 degrees.
