दिल्याप्रमाणे:

षटकोणाच्या पाच कोनांचे माप प्रत्येकी 116° आहे.

वापरलेले सूत्र:

कोणत्याही सुसम बहुभुजाचे एकूण कोण = (n - 2)× 180

गणना:

षटकोनामधील अंतर्गत कोनाची बेरीज (n = 6)

⇒ (6 - 2)× 180

⇒ 720o

प्रश्नानुसार,

पाच कोन 116° × 5 = 580°

उर्वरित कोन = 720° - 580°

⇒ 140° 

∴ उर्वरित कोनाचे माप 140आहे.
