Question

one angle of a 7 sided polygon is 714 degree and each of the Other 6 angles is X degree find x​

Answer 1

The sum of all interior angles of a polygon = (1260-360)° = 900°

Hence, the sum of the rest 6 angles = (900-714)° = 186°

Thus the value of x = 186/6 = 31°

HOPE THIS COULD HELP!!!

Answer 2

714+x=900

6x=900-714=186

x=186/6=31
