Find the value of the variable.
Zielflug [23.3K]

Answer:

x = 8, y = 8\sqrt{2}

Step-by-step explanation:

a^2+b^2=c^2

8^2+8^2=c^2      Both 8 and x sides are congruent so they're equal.

64+64=c^2      Add 64 + 64.

c^2=128           Square root 128

c^2=8\sqrt{2}

Final answers: x = 8, y = 8\sqrt{2}
