Answer:
B.x=94, y=105
Step-by-step explanation:
Let's start with x
x is places in a supplementary angle
supplementary angles are equals to 180 so
180-86=94
Next the y
interior angles have a formula 180(n-2)
so there are 4 sides
180(4-2)
180(2)
=360
add all the angles then subtract it to 360
72+89+94+y=360
255+y=360
y=360-255
y=105
