Answer:

\text{B. }12.6

Step-by-step explanation:

The cut the construction worker makes forms two right triangles. Therefore, we can use the Pythagorean theorem to solve this problem:

The Pythagorean theorem states that for any right triangle, the following is true: a^2+b^2=c^2, where a and b are two legs of the triangle and c is the hypotenuse.

a^2+b^2=c^2,\\12^2+4^2=c^2,\\c^2=160,\\c\approx \boxed{\text{B. }12.6}
