I have 3 triangles joined together with common legs between them. For triangle ABC (the blue one in the diagram below) we know all its angles and the length of all it's sides. For the other two triangles, BCO and ACO (the red ones in the diagram below) we known one side and one angle for each. I want to calculate the unknown sides and angles of triangles BCO and ACO.
How would I go about doing this?
