Find the values of x and y that make k || j and m || n. x = y =

So,
a parallelogram is forming here

then, opposite angels are going to be equal

so,
y = (x+50)°

now,
as you know that sum of all angles of a quadrulateral equals 360°
so,

2 {(x+50)+(x-30)}=360°
(x+50)+(x-30) = 180°
2x + 20 = 180
2x = 160
x = 80°

therefore,

angle y = (x+50) = 80 +50 = 130°
and x = (x-30) = 80 - 30 = 50°

Ithink the answer is a
