This was one of many questions that were asked on the ministry exam Math SN sec 4. How do I find the coordinate for S? Their were no numbers showing on the X or Y axis. Do I use trigonometry?

Hi !

It depends on the informations you got. For example, you could have used the cosine or sine law :

And maybe two of the lines were perpendicular, meaning that you could have found their slope.

If you have any other questions, feel free to ask them !
