Answer:
a > b > c
Step-by-step explanation:
The longest side is the one that sees the angle with the biggest measure
The angles are shown in the image, the third angle is 75 degrees (because the sum of interior angle is equal to 180)
So the list of the sides in descending order is as follows :
a > b > c (a sees angle measure 75, b sees angle measure 70, and c sees angle measure 35)
It is convenient to let a calculator do the math.

I prefer using the RREF function to put the augmented matrix into reduced row-echelon form. If the equations are dependent or inconsistent, using that method tells you so without giving a matrix inversion error.
Answer: A. one real solution
This solution is a double root (it repeats itself). An example would be x^2-8x+16 = 0 has the only solution x = 4.
A square has 4 sides, so 128 in. Squared divided by the 4 sides, would then equal 32 in. Squared for the approximate side length of a square game board
-1/2+2 (-9/4)
Reduce the fraction by dividing the numerator and denominator by 2
-1/2+1 (-9/2)
Multiply the values
-1/2 - 9/2
Bring the values to the common denominator
(-1-9)/2
Calculate the difference
-10/2
Reduce the fraction by dividing the numerator and denominator by 2
-5.
