Problem 9. I know I somehow mess up everything. I think I did the pythagorean theorem right. I have the altitude, so what next?

Triangles CRT and ART are both special triangles and they're the 60,30,90 ones?

How did you determine this?
But my question is more about the relationship between the triangles.
