Question

One angle of a seven sided polygon is 108° and each of the other six angles is X°. The value of X is :​

Answer 1

Step-by-step explanation:

108° + 6 x =( 7-2 ) × 180

108° + 6x = 5× 180

108°+ 6x = 900

6x =900-108 =792

x = 792/6 = 132 °

Answer 2

108° + 6x = 900

(sum of interior angles of heptagon is 900°)

6x= 900 - 108 = 792

x = 792/6 = 132

so the answer is 132

x is equal to 132
