Answer:
x =
Step-by-step explanation:
The given figure is a trapezium which is a quadrilateral with four sides.
But,
Sum of angles in a quadrilateral = (n - 2) x 180
where n is the number of sides.
For a quadrilateral, n = 4. So that,
Sum of angles in a quadrilateral = (4 - 2) x 180
= 2 x 180
=
The sum of angles in a quadrilateral is .
Thus,
+ + + =
+ =
= -
=
The value of x is .
