I would start by drawing a better picture, that is at least somewhat to scale. (Your equilateral triangles don't look equilateral, and that may affect your thinking.)On the sides BC and AC of triangle ABC, equilateral triangles BCA1 and ACB1 are constructed externally. Point M is the midpoint of side AB and O is the center of triangle BCA1. Find the angles of triangle OMB1.
......and O is the center of triangle BCA1....
