Question

In a quadrilateral ABCD, AB //CD and AD=BC=7cm .If angle A = 70 , find the other angles

Answer 1

in a quadrilateral two sides are parallel to each other.
AS IN THE ATTACHMENT
If AB // CD and AC is their transversal then
<A + <B = 180 ( int. same . side .on transversal )
70 + <B = 180
<B = 180-70
<B = 110
but <A = <D ( opp . angles are equal in a quadrilateral if 2 sides are parallel )
=) <D = 70
=) <C = 110

I HOPE IT HELPS YOU

Answer 2

Answer:

answer of this question is 110

Step-by-step explanation:

x+70=180

x=180-70

x=110
