Question

Find the length of x. Assume the triangles are similar.A. 25B. 12C. 19D. 20

Answer 1

Since those triangles are similar, the ratio between their corresponding sides must be equal. From this statement, we have the following equation for x:

`(x)/(10)=(12)/(6)`

Solving for x:

`\begin{gathered} (x)/(10)=(12)/(6) \\ x=(12)/(6)*10 \\ x=2*10 \\ x=20 \end{gathered}`

The length of x is equal to 20. The answer is option D.
