vazorg [7]2 years ago
5 0

Answer:The  pair of angles must be supplementary are ∠2 and ∠5.

The correct option is (B)

What is supplementary angle?

Two angles are called supplementary when their measures add up to 180 degrees.

Given that:

∠2=90 and ∠5=90

So,

∠2+∠5

=90+90

=180

Hence, angle 2 and 5 makes supplementary angles.
