Given a ratio of sides of a triangle and perimeter find the measure of the sides

The video tutorial explains how to find the actual side lengths of a triangle given the ratio of its sides and the perimeter. It begins by discussing the concept of ratios and their simplification using angles as an example. The tutorial then demonstrates how to solve for actual angles from simplified ratios. Finally, it calculates the actual side lengths of the triangle by setting up an equation with a reduction factor and solving it to match the given perimeter.

What is the value of X when solving the equation 9X + 7X + 5X = 191.1?

What are the actual lengths of the sides of the triangle after applying the reduction factor?

How do you verify that the sum of the sides equals the given perimeter?
