Which angle pairs are supplementary? Check all that apply.
21 and 22
0 24 and 23
0 24 and 25
O 27 and 25
O 23 and 26

Option B, C and E are supplementary angles.

Step-by-step explanation:

We need to find supplementary angles.

Supplementary angles are those angles who sum up to 180 °.

I have attached picture for reference.

Looking at the figure given:

We have supplementary angles:

∠4 and ∠3

∠4 and ∠5

∠5 and ∠6

∠7 and ∠8

∠3 and ∠6

But the options given are: ∠4 and ∠3,∠4 and ∠5, ∠3 and ∠6

So, Option B, C and E are supplementary angles.

168

step-by-step explanation:

i am pretty sure that the answer is 168
