If an interior angle of a regular polygon measures 140*, how many sides does it have?
1 answer:
Answer:
9 sides.
Step-by-step explanation:
N is the # of sides.
140 = ((n-2) x 180) / n
Multiply both sides by n
140 n = (n-2) x 180
Distribute the right side
140 n = 180 n - 360
Subtract 140 n and add 360 to both sides.
40 n = 360
n = 9
