Answer:
20°
Step-by-step explanation:
A pentagon's interior has a total of 540°. So, you must figure out the fifth angle.
Use the equation:
540°-85°-90°-95°-110°= fifth interior angle
You should get that the fifth interior angle equals 160°.
The <em>largest </em>interior angle will have the <em>smallest </em>exterior angle. In this case, it is the fifth interior angle, 160°.
An exterior angle added to its interior angle equals 180°.
So use the equation:
180°-160°=exterior angle.
You should get that the exterior angle is 20°.
