Find the missing values of the variables. The diagram is not to scale.

RideAnS [48]

Answer:

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
