Answer:
B. x = 28, y = 47
Explanation:
Given that PQRS is a square
We know that , In a square each vertex is a right angle that is 90 degree
So we set two equations
3y+ 6 = 90 and 2x -4 = 90
Solve for x and y
3y + 6 = 90
Subtract 6 from both sides
3y = 84
divide by 3 on both sides
y = 28
2x - 4 = 90
Add 4 on both sides
2x= 94
Divide by 2 on both sides
x= 47
