(2) Find the length of the missing side of the right triangle. (A) \( \sqrt{12.96} \) (B) \( \sqrt{5.6} \) (C) \( \sqrt{16.96} \) (D) \( \sqrt{7.2} \)

Step 1 ：Given right triangle with sides: (A) \( \sqrt{12.96} \), (B) \( \sqrt{5.6} \), (C) \( \sqrt{16.96} \), (D) \( \sqrt{7.2} \)

Step 2 ：Use Pythagorean theorem: \(a^2 + b^2 = c^2\) in right triangle

Step 3 ：Choose \( \sqrt{16.96} \) as length of the missing side because only \( (\sqrt{12.96})^2 + (\sqrt{5.6})^2 = (\sqrt{16.96})^2 \)
