Can anyone explain the solution to this question please?

So I came across this question as my friend asked me for help...Is the pythagoras theorem used in this case? or are there any other solutions? I will be really grateful if you can help.Thanks :)

Because it's vectors you don't need to use Pythagoras' theorem because edges add together eg. DR-> =1/3c +a. But need to include directions. Not sure about solution though.
