Look at the two triangular signboards below.

The first sign board has length of sides equal to (8y - 3) cm and (x + 7) cm. The second sign board is obtained by rotating the first sign board by 180 degrees clockwise.

Which pair of equations is correct? (6 points)

x =1 and y = 8
x = 38 and y =9
x = 45 and y = 69
x = 62 and y = 6
