Question

Scale and Similarity:Question 10 Given that the two right triangles below are similar, what is the value of x?

Answer 1

To solve the exercise you can apply the ratio

`(5)/(2)=(x)/(4)`

Now, multiply by 4 on both sides of the equation

`\begin{gathered} (5)/(2)\cdot4=(x)/(4)\cdot4 \\ (5\cdot4)/(2)=x \\ (20)/(2)=x \\ 10=x \end{gathered}`

Therefore, the value of x is 10.
