Answer 1

We have an equilateral triangle with sides 1.8*k*s, 3.5+6.1*k and k+1.5.

As the three sides have the same value we can take the expression of one side and make it equal to the expression of another side.

We can find the value of k as:

`\begin{gathered} 3.5+6.1k=k+1.5 \\ 6.1k-k=1.5-3.5 \\ 5.1k=-2 \\ k=-(2)/(5.1) \\ k=-(20)/(51) \end{gathered}`

We then can include the other side to find the value of s:
