Four angles of a nine sided polygon are 1450 each and the remaining angles areequal. Find the value of each equal angle.​

Answer»

ANSWER:

ANSWER

Two ANGLES of an eight sided polygon are 142

o

and 176

o

and the REMAINING angles are EQUAL to each other. Let each equal angle =x

Sum of all interior angles of a polygon is = 180

o

(n−2)=180

o

(8−2)=1080

o

Now,

142

o

+176

o

+(8−2)×x=1080

o

⟹ 6x=762

⟹x=127

o

Each equal angle = 127
