From the given figure
Since every two opposite sides are parallel
AB // DC
AD // BC
Then the given quadrilateral is a parallelogram
ABCD is a parallelogram
From the properties of the parallelogram,
Every 2 opposite sides are equal in length, then
AB = DC
AB = x + 2, and DC = 13, then
x + 2 = 13
Subtract 2 from both sides to find x
x + 2 - 2 = 13 - 2
x = 11
Since the opposite angles in the parallelogram are equal in measures
Since
m
Since m
y = 70
The value of x is 11 and the value of y is 70
