Question

multiple-choice question what is the missing length? 169 84.5 13

Explanation:

To solve this, we assume it's a right triangle problem (Pythagorean theorem). Let's say the legs are 5 and 12 (common Pythagorean triple).

Step1: Apply Pythagorean theorem

The Pythagorean theorem is \( a^2 + b^2 = c^2 \), where \( a = 5 \), \( b = 12 \).
\( 5^2 + 12^2 = 25 + 144 = 169 \), then \( c = \sqrt{169} = 13 \).

Answer:

13 (the option with 13)
