@gandolf: Sure, if you are given the lengths of the sides (or their ratio) you can easily determine all the lengths and angles involved. To begin to think about it, try drawing lines that extend the sides of the triangle and draw the lines connecting the 'corners.'

comment Find all the five digit primes with this property
@draks: You interpreted it as product of the digits is neither zero nor squarefree...? I also got 6021.

comment Applying Möbius Inversion to $\Pi(x)$ and $\pi(x)$
But I think Edwards actually does that calculation in detail on p. 34. Then at 217-18 he has a discussion of the inversion generally--its derivation. This corresponds to section 2.7 in Apostol's Intro to Analytic Number Theory. A more general (and relevant) statement of inversion is $G(x) =\sum_{n\leq x}\alpha(n)F(x/n) \leftrightarrow F(x)=\sum \mu(n)\alpha(n)G(x/n).$
