Question

The sum of interior angles of a regular polygon is 1260°.Find the measure of each interior angle of the polygon. *
1 point
A. 180 deg
B. 140 deg
C. 90 deg
D. 210 deg​

Answer 1

Answer:

option B is correct

sum of interior angles of poly gon = (n - 2) × 180

1260 = (n - 2)×180

n - 2 = 7

n = 9

now exterior angle = 360/n = 360/9 = 40

Hence interior angle = 180 - 40 = 140

Answer 2

Answer:

the answer is 140 degrees

Step-by-step explanation:

polygon here is a nanogon . SO,

1260/9 = interior angles

140° = interior angles
