Answer:
110°
Step-by-step explanation:
The sum of the interior angles of an octagon is 1080° → (8 - 2) × 180. We can now do 1080 - (160 × 4) to find the total of the remaining four angles: 1080 - 640 = 440°. Finally, we can divide 440 by 4 to find the size of one of the four remaining angles: 440 ÷ 4 = 110°
Hope this helps!
