In a square, all four sides are equal, so you would take the perimeter and divide by 4.
(12x - 32)/4 = 3x - 8 feet
1st image: 1, angle 1 is next to angle 2.
2nd image: since those angels are parrelled they’re the same number, so you just need to solve the equation.
6x+2=56
6x=54
6x/6 = 54/6
x=9
hope that helps!
