Answer 1

Step-by-step explanation:

1)The angle of supplement is 180°

2) The angle of compliment is 90°

Answer 2

Step-by-step explanation:

1___Let x be two equal angles of its supplement.

Therefore, x+x=180 [Supplementary angles]

⇒2x=180°

⇒x= 2/180°

=90°

Thus, 90° is equal to its supplement

11__one of the two equal complementary angles be x.

∴x+x=90°

⇒2x=90°

⇒x= 2/90°=45°

Thus, 45° is equal to its complement.
