Complementary angles add up to 90 degrees. Congruent angles are equal to one another (have the same degrees) Supplementary angles add up to 180 degrees.

124 + 56 = 180

The angles are supplementary

Answer:

The two angles are supplementary.

Step-by-step explanation:

Given ∠ABC measures 124° and ∠MNO measures 56°. we have to find the relation between two angles.

∠ABC=124°

∠MNO=56°

∠ABC+∠MNO=124°+56°=180°

Supplementary angles are either of two angles which add up to give the sum of 180°

As above given two angles gives the sum 180°

⇒ Both angles ∠ABC and ∠MNO are supplementary.

Option B) is correct.
