Question

What is the sum of an interior angle and its adjacent exterior angle?

a.30°
b.90°
c.180°
d.360°

Answer 1

Hello!

The sum of an interior angle and its adjacent exterior angle is 180°

Answer 2

The answer is:

C) 180°

Work/explanation:

The sum of an interior angle and its adjacent exterior angle is
`\sf{180^o}`, which means that an interior angles and its adjacent exterior angle form a linear pair.

This also means that the angles are supplementary, because they add up to
`\sf{180^o}`.

Hence, the right choice is C.
