Answer:
Using Pythagoras theorem we can find the missing length.
5^2 + 13^2
25 + 169 = 194
√194 = 13.9283882772 = around 13
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
