Question

8. If angles A, B, C and D of the quadrilateral ABCD, taken in order, are in the ratio 3.7 6.4.
then name the type of quadrilateral ABCD.
​

Answer 1

Answer:

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

20x=360

x=360/20

x=18

Answer 2

Step-by-step explanation:

we know that sum of all angles in a quadrilateral is 360

let the angles be X

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

20x =360

X=360/20

X=18

3x=54

7x=126

6x=108

4x=72

this quad is a trapezium as in a trapezium 2 angles are supplementary
