C. 13
D. 15
Solution
Solution Steps
Step 1: Understand the Problem
We are given two sides of a right triangle, \(5\) and \(12\), and we need to find the missing side that completes the Pythagorean triple. The options provided are \(17\), \(14\), \(13\), and \(15\).
Step 2: Recall the Pythagorean Theorem
The Pythagorean theorem states that for a right triangle with sides \(a\), \(b\), and hypotenuse \(c\), the relationship is given by:
\[
a^2 + b^2 = c^2
\]
Step 3: Calculate the Missing Side
Given the sides \(5\) and \(12\), we assume these are the two shorter sides, and we need to find the hypotenuse \(c\).
\[
5^2 + 12^2 = c^2
\]
Calculate \(5^2\) and \(12^2\):
\[
5^2 = 25
\]
\[
12^2 = 144
\]
Add these values:
\[
25 + 144 = 169
\]
Now, solve for \(c\):
\[
c^2 = 169 \implies c = \sqrt{169} = 13
\]
Final Answer
The missing side length that completes the Pythagorean triple is \(\boxed{13}\). Therefore, the answer is C.
