Question

If a triangle a b c d of the quadrilateral abcd taken in ordee , are in the ratio 3:7:6:4, then name the type of quadrilateral abcd

Answer 1

let

a=3x

b=7x

c=6x

d=4x

sum of angles in quadrilateral is 360 degree

then,

3x+7x+6x+4x=360

20x=360

x=360/20

x=18degree

then a=3*18

=54

b=7*18

,=126

c=6*18

=108

d=4*18

=72
