Answer:
9 centimeters
Step-by-step explanation:
Step 1: State your variables
We know 2 sides are equal so we let thos sides be represented by 'x'
Step 2: Solve
Set the 2 variables plus 6 equal to the prerimeter of the triangle and solve for 'x'
[tex]2x+6=24\\2x=18\\\frac{2x}{2}=\frac{18}{2}\\x=9[/tex]
Step 3: Therefore Statement
Therefore the side length of the 2 similar sides is equal to 9 centimeters
