Question

The angles of a quadrilateral are in the ratio 2 : 3 : 6 : 7. Find the smallest angle of quadrilateral.

Answer 1

sum of ratio of angles is -2x+3x+6x+7x=360
                                          18x  =360
                                           x  =360/18
                                           x =20
putting x=20
then    2x =2*20= 40
           3x =3*20 =60
            6x=6*20 =120
             7x =7*20 =140
therefor the smallest angle is 40

Answer 2

2;3;6;7 
condsider them as 2x,3x,6x,7x add them that equals to=18x=360

x=20 and the smallest angle is 40
