Question

PO Triangle ABC is similar to triangular DEF. What is the value of x?

Answer 1

If triangle ABC is similar to DEF then the ratio between the sides will be a constant so we can get the expression:

`(15)/(30)=(x)/(36)`

and we solve for x so:

`\begin{gathered} x=(36\cdot15)/(30) \\ x=18 \end{gathered}`
