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

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 |
