Question:
In Figure 2, ABCD is a parallelogram. Find the values of x and y.
Solution:
The given parallelogram is
We have to find the value of x and y.
We know that if two diagonals are drawn in a parallelogram, then the intersection points is the mid-point of the two diagonals. Therefore, we have two equations as follow
x + y = 9…… (1)
x − y = 5…… (2)
Now, add the equation (1) and equation (2), we get
$2 x=14$
$\Rightarrow \quad x=7$
Now, we are going to put the value of x in equation (1), we get
$7+y=9$
$\Rightarrow y=2$
Hence the value of $x$ and $y$ are $x=7$ and $y=2$
