Answer:
x = 25°
Explanation:
First, let us find the value of y. ( Refer to the attachment )
We know that,
Angles in a straight line are added up to 180° degrees.
Therefore,
123 + y = 180
y = 180 - 123
y = 57°
And now let us find the value of x.
We know that,
The sum of the interior angles in a quadrilateral is 360°.
Therefore,
96 + 5x + 3x + 7 + 57 = 360
160 + 8x = 360
8x = 360 - 160
8x = 200
x = 25°
