???????????????????? "measure av the angel" ????????????????

yu must meen HOW BIG, or SIZE

???????????????? "interior angel" ?????????????? me ges yu meen INSIDE angel

????????????? "exterior angel" ????????????? must be the OUTSIDE angel

me assume inside angel=14*outside angel

inside +outside=180 deg, so x+14x=180, so 15x=180, so x=12

inside angel=14*12=168 deg...also=180-12

30 side regular polygon giv outside angel=12 deg
