Each exterior angle of a regular polygon is 40 degrees. How many sides does it have?
Answer and explanation
Correct answer: B. 9
- Step 1: The exterior angles of any polygon add up to 360 degrees.
- Step 2: Number of sides = 360 / 40 = 9.
Answer
9.
Why not the others: 8 sides would have 45 degree exterior angles, 10 sides 36 degrees and 12 sides 30 degrees.
