M2: Centre of mass exam question (OCR) help needed

Hi there, i'm really having a struggle with question 3 of this exam paper:

The mark scheme is very vague as is the textbook we use, therefore I would really appreciate some guidance as to the method I should be using. Many thanks in advance!

Calculate a point for tge center of mass, I would then create a Cartesian equasion for AC and use the perpendicular rule with y-y1=m(x-x1) to find the intercept of those 2 lines. And use the 2 points with pythagorous to find the distance.

Then you can use basic trig to do the second part.
