Find the value of x in the figure at the right.
A. x = 36
B. x = 12
C. x = 10
D. x = 9.
Side 1: x - 4
Side 2: x
Side 3: 9
Side 4: 6
Show your work.
From the figure, we can see that the opposite sides of a quadrilateral are equal.
Therefore,
x - 4 = 9
x = 9 + 4
x = 13
Thus, the correct answer is not given in the options provided.
