Question

if angle a b c d of a quadrilateral abcd taken in order,are in the ratio 3:7:6:4,then abcd is

Answer 1

we know that
addition of all angle of quadrilateral=360
3x+7x+4x+6x=360

=20x=360x
=x=18


angles are
54 .126 108.72
follow me please

Answer 2

Step-by-step explanation:

Let angles of quadrilateral ABCD be 3x, 7x, 6x, 4x.

Sum of all angle of quadrilateral=360°

3x+7x+6x+4x=360°

20x=360

x=18°

Therefore, angles of quadrilateral are 54°. 126°, 108°, 72°.

Hence ABCD is a trapezium.
