Answer:
exterior angle = 18°
Step-by-step explanation:
The sum of an interior angle and it's adjacent exterior angle is 180°
That's
interior angle + exterior angle = 180°
From the question
interior angle = 162°
exterior angle = 180 - interior angle
Substitute the value into the above formula
That's
exterior angle = 180 - 162
We have the final answer as
exterior angle = 18°
