Question

What is the suppliment of an angle whose measure is 99 degree

Answer 1

Answer:

Step-by-step explanation:

Let the required angle be x

The sum of supplementary angles is 180°.

So,

99°+ x° =180°

x° = 180° - 99°

x° = 81°

Answer 2

Sum of two angle is 180° us called supplimentry angle

180°-99°= 81°
