So BE = 2 BM

Now, since ABE is an equilateral triangle,
Its sides are of the same length.

So AB = BE = AE

AB also = 2 BM , since AB = BE

But we also know AB is twice the length of BC.

So AB = 2 BC

Since AB = 2 BC and AB = 2 BM,

2 BC = 2 BM

Hence triangle BMC is an isosceles triangle.

From here, it should be easy to solve.
