.
Step-by-step explanation:
Given:
We need to find .
Solution:
Now we can see that given figure is a rectangle with diagonals drawn in it.
So by properties of rectangle which states that;
"All angles of a rectangle are 90°."
So we can say that;
But
Substituting the values we get;
Subtracting both side by by 31 we get;
Hence .
