M is the midpoint of the side AB in an equilateral triangle ABC. The point D on the side BC is such that BD:DC=3:1. On the line passing through C and parallel to MD there is a point T inside the triangle ABC such that ∠ CTA=150. Find the ∠ MTD.

I haven't been able to double check but it doesn't look like the answer is nice: ∠ MTD=123.996535529
