Answer:
B
Step-by-step explanation:
107 and y form a straight angle and are supplementary, thus
107 + y = 180 ( subtract 107 from both sides )
y = 73
The sum of the interior angles of a quadrilateral = 360°
Sum the given angles and equate to 360
117 + 79 + 73 + x = 360, that is
269 + x = 360 ( subtract 269 from both sides )
x = 91
Thus x = 91, y = 73 → B
