The picture shows enough information to indicate the smaller right triangle. a is the longer leg of this small triangle and x is the hypotenuse of this small triangle.

Although I do not remember the official theorem, this smaller right triangle is also a 30-60-90 right triangle, similar to the main right triangle.

The other leg of this small right triangle is in length.
directly according to pythagorean theorem

and you can substitute a=6 and evaluate x.
