**Answer:**

Y = 16

z = 7.2

**Step-by-step explanation:**

y = √(12.8²+9.6²) = √256 = 16

x² = 9.6²+z² .....(1)

(12.8+z)² = 16²+x².... (2)

Substituting value of x from equation 1,

(12.8+z)² = 16²+9.6²+z²

12.8² +z² +2×12.8×z = 16²+9.6²+z²

163.84 + 25.6z = 348.16

25.6z = 348.16-163.84

25.6z = 184.32

z = 184.32/25.6

z = 7.2

Putting value of z in equation 1,

x² = 9.6²+7.2²

x= √144

x = 12
