Question

7. The measure of each of the interior angles of a regular polygon having an angle sum of 1260° is
a. 162°
b. 126°.
C. 144°
d. 140°
​

Answer 1

Answer:

d.140°

Step-by-step explanation:

n=number of sides of a polygon

(n-2)×180°=1260°

(n-2)=1260°/180°

(n-2)=7

n=7+2=9

n=9

1260°/9=140°

total sum of angles/number of sides=measure of each angle
