Dear Student,
● Answer -
45°, 90°, 90° and 135°
◆ Explanation -
Given that 3 angles are in ratio 1:2:3. Let x be common multiple such that angles become x, 2x and 3x.
We have, sum of smallest angle and greatest angle is 180 degree.
x + 3x = 180°
4x = 180°
x = 180°/4
x = 45°
These 3 angles become,
x = 45°
2x = 2×45 = 90°
3x = 3×45 = 135°
Sum of all angles of quadrilateral is 360°.
45° + 90° + 135° + 4th angle = 360°
270° + 4th angle = 360°
4th angle = 360° - 270°
4th angle = 90°
So four angles of quadrilateral are 45°, 90°, 90° and 135°.
Hope this helps you...
