നൽകിയിരിക്കുന്നത്:

ഒരു ഷഡ്ഭുജത്തിന്റെ അഞ്ച് കോണുകളിൽ ഓരോന്നിന്റെയും അളവ് 116° വീതം ആണ്.

ഉപയോഗിച്ച സൂത്രവാക്യം:

ഏതെങ്കിലും സാധാരണ ബഹുഭുജത്തിന്റെ ആകെ കോൺ = (n - 2)× 180

കണക്കുകൂട്ടൽ:

ഒരു ഷഡ്ഭുജത്തിലെ ആന്തരിക കോണുകളുടെ ആകെത്തുക (n = 6)

⇒ (6 - 2)× 180

⇒ 720o

ചോദ്യം അനുസരിച്ച്,

അഞ്ച് കോണുകൾ 116° × 5 = 580° ആണ്

ശേഷിക്കുന്ന കോൺ = 720° - 580°

⇒ 140°

∴ ശേഷിക്കുന്ന കോണിന്റെ അളവ് 140o ആണ്.
