Answer:

Using Pythagoras theorem we can find the missing length.

5^2 + 13^2

25 + 169 = 194

√194 = 13.9283882772 = around 13

Answer:

A

Step-by-step explanation:

Using Pythagoras' identity in the right triangle

x² + 5² = 13²

x² + 25 = 169 ( subtract 25 from both sides )

x² = 144 ( take the square root of both sides )

x = [tex]\sqrt{144}[/tex] = 12 → A
