Four interior angles of a pentagon measure 85°, 90°, 95°, and 110°. What is the smallest measure of the pentagon's exterior angles?

A 5°

B 20°

C 70°

D 85°

An interior and exterior angle add up to 180 degrees.

+

The sum of all the angles in a pentagon is 540 degrees, using that find the missing angle:

85+90+95+110=380

540-380=160

Then, find the exterior angle measure for 160 degrees (160 is interior):

180-160=20

The answer is B) 20
