M2 Centre of Mass Question

Hi

I really need help on this question

There's a triangular frame and it has length of 24cm. So AB is 6cm, BC is 8cm and AC is 10cm. Its a uniform wire. I need to find out the centre or mass from AB and BC

A drawing would help? What kind of triangle is it? Right-angled, isosceles?

If AB, AC and BC are parts of the wire, then treat each one separately as a body of its own. Each one's mass would be the same as its length. Meaning AB's mass = 6, etc..
