Supplementary angles add up to 180° (a straight line).

∠MKN and ∠OKN are supplementary angles because they form the straight line that goes diagonally more downards.

Hey there! :)

Supplementary angles measure 180° = straight angle

There are 2 angles that measure 180°:

- ∠MKN
- ∠OKN

Both of those angles add up to 180° because they make a straight angle.

Answer ⇒ ∠MKN and ∠OKN ⇒ Last choice

Hope this helps :)
