दिले:

बहुभुजाच्या सर्व अंतर्गत कोनांची बेरीज बाह्य कोनांच्या बेरजेपेक्षा 200% जास्त आहे.

वापरलेले सूत्र:

बहुभुजाच्या सर्व आतील कोनांची बेरीज = (n - 2) × 180°

जेथे n = बाजूंची संख्या

गणना:

प्रश्नानुसार,

बहुभुजाचे आतील कोन असल्यास बेरीज

= 360° पैकी 300%

= 3 × 360°

= 1080°

बहुभुजाच्या सर्व आतील कोनांची बेरीज = (n - 2) × 180°

⇒ 1080° = (n - 2) × 180°

⇒ (1080°/180°) = (n - 2)

⇒ 6 = n - 2

⇒ n = 8

आता, प्रत्येक आतील कोन x = 1080°/8 = 135°

∴ x चे आवश्यक माप 135° आहे.
