The Sun, at a distance of 149.6 million km from Earth, subtends about the same angle in the sky as does the Moon, with a radius of 1737 km at a distance of 384,400 km from Earth. Use this information to find the radius of the Sun in km. Round your answer to three significant figures.

Can someone show me (in detail) how to solve this, please?

I don't know how to explain this without a sketch, so I made a sketch and uploaded it here: http://lovelyhufflepuff.deviantart.com/art/Algebra-340872547
I hope it helps u and that it is detailed enough.
The solution ( about 2 170 000 000 km)is not quite the same as http://en.wikipedia.org/wiki/Solar_radius but i think close enough.
