Answer 1

Since the angles in triangle ACM indicate that it is a 30-60-90 triangle, we know that the other two sides of triangle ACM are 20 and 10 (30-60-90 triangles have a very specific side coefficient). This means that the sides of this triangle have side lengths 40, 10, and $20\sqrt{3}$. Adding these together you get 50+$20\sqrt{3}$. Hope this helps!
