Answer:
3
Step-by-step explanation:
It would be c 25/2
Sorry, I can actually understand what you were asking in the comments
F(3) = (<span>√3 -7)/6
f(3) = (1.732 - 7)/6
f(3) = 5.268 / 6
f(3) = 0.878 ...nearest thousandths

The pythagorean theorem states: a² + b² = c²
Where c is the longest side (hypotenuse).
So we plug in and solve for the third side "b".
a = 12, c = 13, so:
12² + b² = 13²
144 + b² = 169
b² = 169 - 144
b² = 25
b = 5
We can double check the pythagorean theorem to make sure:
12² + 5² = 13²
144 + 25 = 169
So the unknown side is definitely 5.
