To solve this problem, we introduce the conditional variable “X”, through which we denote the length of the AC side of the triangle.

The first step is to determine the length of the BC side of the triangle.

As a result, we get that the length of the BC side will be equal to 27/3 = 9 centimeters.

Then, based on the data of the problem, we will compose the following equation: X + 27 + 9 = 61.

Solving this equation, we get X equal to 25 centimeters.

Answer: The length of the AC side of the triangle is 25 centimeters.
