Timedd
name a pair of supplementary angles in the diagram.
a< 4 and < 5
b < 2 and < 3
c < 7 and < 9
d < 1 and < 2

Step-by-step explanation:

In the given figure we have to identify the supplementary angle. We will go through each options given

Option (A) ⇒ ∠4 + ∠5

                      They are complementary angles

                     ∠4 + ∠5 = 90°

Option (B) ⇒ ∠2 and ∠3

                  They are supplementary angles

                  ∠2 +∠3 = 180° ( angles on a point of a line)

Option (C) ⇒ ∠7 and ∠9

                     ∠7 = ∠9

                   They are opposite angle.

Option (D) ⇒ ∠1 and ∠2

                  They are not on a point of line

                  so they are not complementary
