Step-by-step explanation:
let the angles be 2x , 3x , 6x, 7x.
- 2x +3x+6x+7x =360 (being sum of angle of quadrilateral)
- 18x=360
- x=360/18
- ×=20
Now,
- 2x= 2×20 = 40
- 3x=3×20 =60
- 6x=6×20 =120
- 7x=7×20 =140

Given :-
- Shape = Quadrilateral
- The four angle of a quadrilateral are in the ratio of 2:3:6:7.
To Find :-
- The Measure of all the Angles
Solution :-
⟾ Let the First angle be 2x
⟾ Let the Second angle be 3x
⟾ Let the Third angle be 6x
⟾ Let the Fourth angle be 7x
❏ As we know that, Sum of all the angles of a Quadrilateral is 360° [ Angle sum Property of Quadrilateral ] .
According to the Situation :
➞ 2x + 3x + 6x + 7x = 360
➞ 5x + 13x = 360
➞ 18x = 360
➞ x = 360 / 18
➞ x = 20°
________________
Verification :-
➥ 2x + 3x + 6x + 7x = 360
➥ 2 × 20 + 3 × 20 + 6 × 20 + 7 × 20 = 360
➥ 40 + 60 + 120 + 140 = 360
➥ 100 + 260 = 360
➥ 360 = 360
Hence Verified
________________
Therefore :
- 1st Angle = 2x = 2 × 20 = 40°
- 2nd Angle = 3x = 3 × 20 = 60°
- 3rd Angle = 6x = 6 × 20 = 120°
- 4th Angle = 7x = 7 × 20 = 140°
