Answer:
The answer is 2.1+2*x=7.5
Step-by-step explanation:
If the isosceles triangles shortest side measures 2.1m, measurement of one of the other sides with multiplication by 2 need to give the perimeter of the triangle. Therefore, equation that gives the perimeter of the triangle can be written as:
[tex]y+2*x=7.5[/tex]
We know that y=2.1 then equation will be:
[tex]2.1+2*x=7.5[/tex]
