Question

Triangle Similarity What is the value of x?

Answer 1

To solve this you can make a proportion where the matching sides will correspond to each other. It should look something like this:

`(AC)/(PD) =(CR)/(DR)`

`(10)/(15) =(x)/(42)`

Now you must cross multiply

10*42 = 15*x

420= 15x

To isolate x divide 15 to both sides

420/15 = 15x/15

28 = x

Hope this helped!
