Question

This is so confusing i do not understand what this even is

Answer 1

Since the triangle is dilated, the sides of the original triangle are stretched. Since J'K' is the length of one side of the triangle after the dilation, we have that:

`\begin{gathered} J^(\prime)K^(\prime)=(4)/(3)JK,J^(\prime)K^(\prime)=13.5 \\ \Rightarrow13.5=(4)/(3)JK \\ \Rightarrow JK=(3\cdot13.5)/(4)=10.125 \end{gathered}`

Then, the answer is 10.125
