What does x equal and what does why equal?

1.
x^2 + 6.4^2 = 8^2
x^2 = 40.96 = 64
x^2 = 64 -40.96
x^2 = 23.04
x = sqrt(23.04) = 4.8
2. y=
y^2 + 3^2 = 5^2
y^2 +9 = 25
y^2 = 25-9
y^2 = 16
y = sqrt(16) = 4
Answer:
x^2 + 6.4^2 = 8^2
x^2 = 40.96 = 64
x^2 = 64 -40.96
x^2 = 23.04
x = sqrt(23.04) = 4.8
y=
y^2 + 3^2 = 5^2
y^2 +9 = 25
y^2 = 25-9
y^2 = 16
y = sqrt(16) = 4
