Here is a pic to get you started.

 

You have to use similar triangles to work out the length of x.

 

then continue from there.

Dragan, my answer was a teaching answer. 

You have come in over the top of me and given the child a cheat answer.

There are lots of questions here and if you answer first you are welcome to answer however you want but please do not override my teaching answers.

You do not need to examine previous answers.

My answer was there many hours before you started yours.

It would be impossible for you to overlook that an answer already existed.

 

 

By answering in full you reinforced what the students already know.

This is the best cheat site available.

They can see that even key answerers will not support each other in trying to change this reputation.

 

Do you notice that the original asker has been silent?

He/she has copied your answer and handed in the assignment.
