Download Solution PDFகொடுக்கப்பட்டது:
கோணம் 1 = கோணம் 2
கோணம் 3 = 780
பயன்படுத்தப்பட்ட கருத்து:
ஒரு முக்கோணத்தின் அனைத்து கோணங்களின் கூட்டுத்தொகை 1800 ஆகும்.
கணக்கீடு:
நாம், கோணம் 1 = கோணம் 2 = x என வைத்துக்கொள்வோம்.
இப்போது,
x + x + 780 = 1800
2x = 180 - 78
2x = 102
x = 51
எனவே, சரியான பதில் '510'.
