Question

Triangle ABC is similar to triangle FGH. What is the value of x in centimeters?A. 22.5 cmB. 21 cmC. 10.8 cmD. 30 cm

Answer 1

first we can calculate the coefisient between the triangles so we use two sides that we know so:

`(13.5)/(9)=2.25`

So now we can calculate x like:

`\begin{gathered} x=2.25\cdot15 \\ x=33.75 \end{gathered}`
