This question is from textbook Answer by checkley71(8403)   (Show Source): You can put this solution on YOUR website!the sum of all interior angles of an 8 sided figure is: 180(8-2) 180*6 1080 what you have are 7 of these angles which total: 90+105+125+130+150+155+165=920 so the missing angle must be: 1080-920=160 degrees.
