. If three angle of a quadrilateral are in the ratio 2: 3: 5 and fourth angle is 130
find the angles​

Respuesta :

Total ratio = 2 + 3 + 5 = 10
Sum of angles in a quadrilateral is 360
4th angle = 130
360 - 130 = 230
Sum of remaining 3 angles must be equal to 230
1st angle 2/10 * 230 = 46
2nd angle 3/10 * 230 = 69
3rd angle 5/10 * 230 = 115
Adding all angles together 46 + 69 +115 + 130 = 360
