The sum of the interior angles of any quadrilateral is 360°.
So,
90° + 90° + 52° + x = 360°
=> 232° + x = 360°
=> x = 360° - 232°
=> x = 128°
Given :
y= -8x-6
y= -3x +4
By solving it, we get,
-8x-6 = -3x+4

Substituting the value of "x" in second given equation,


By solving it, we get,

Hence, the values are :-

I guess 3 and 19? Or are you asking a different question?
Answer:
I don't know either but thanks for asking me
