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 is = 127

o
