Answer:
The answer is 150 degree.
The area = L*L=9 or 3*3=9
Which means that each sides length equals 3 if it is a perfect square.

The difference is the result of a subtraction problem.
We are given two values that are being subtracted: 54 and a number, represented by 
So, represent this mathematically with
