Q 6: If ABCD is a quadrilateral. Then x = ​

Answer 1

Step-by-step explanation:

We know the sum of all int. angles of a quadrilateral ABCD=360°

x+56+x+90=360

2x+146=360

=>2x=214

=> x= 107.

Answer 2

Answer:

Sum of all angles in a quadrilateral = 360⁰

Angles = x,x,56⁰,90⁰

Sum = x+x+56+90 = 360⁰

=》2x+146 = 360⁰

=》2x = 360-146 = 214⁰

=》x = 214/2 = 107⁰.

So, the value of x is 107⁰.
