9 cm

Step-by-step explanation:

Because the triangle in the picture is a right angle triangle, we can use the Pythagorean theorem to solve the unknown side.

The Pythagorean states that if you take the legs of a right triangle and square them and add them up, they will equal the hypotenuse squared.

In a mathematical equation:

In this problem, we know the length of one leg and we know the length of the hypotenuse.

The variables a and b in the equation  are the legs. So, they are interchangeable. But the c variable is the hypotenuse.

Plug in the values.

Solve for b.

b = 9

So, the unknown side is 9 cm long.

ca = ec

cpctc makes it so that corresponding parts of the triangle you proved to be equal are equal, the other options aren't part of the part of the triangles you proved to be equal.
