As we all know that sum of all angles of quadrilateral is 360 degree let ratio = x threfor angles = 14x ,8x ,11x
Hence,
14x + 8x + 11x + 63 = 360
33x + 63 = 360
33x = 360-63
33x = 297
x = 297÷33
x = 9
Largest angle =14x
= 14 ×9 = 126 ans
Hence,
14x + 8x + 11x + 63 = 360
33x + 63 = 360
33x = 360-63
33x = 297
x = 297÷33
x = 9
Largest angle =14x
= 14 ×9 = 126 ans
