Answer 1

Answer:

80degree

Step-by-step explanation:

Answer 2

To find : supplementary angle of $100$ .

Solution :

• When sum of measure of two angles is $180$° then these angles are called as supplementary angles .
• Let suppose , ∠A and ∠B are supplementary angles then ,

      ∠A + ∠B = $180$°

• Let , $x$ be the supplementary angle of $100$  ,
• Then ,

       $x + 100 = 180 \\x = 180- 100 \\ x = 80$

Hence, $80$° is the supplementary angle of $100$°  .
