L-Br, Draw the circles centered at the points A and E and their axis of symmetry CM. Prove that the axis will pass through the point K. Get the arc, which supports the angle X..........I hope that further you solve it yourself, but write me in the other case. |

All right, but I'm still trying. Does not there is an alternative solution without using circles? |
