a) \(\frac{l}{a}=\frac{m}{b}=\frac{n}{c}=μ\)
b) \(\frac{l}{a}=\frac{m}{b}=\frac{n}{c}=μ-1\)
c) \(\frac{l}{a}=\frac{m}{c}=\frac{n}{b}=μ\)
d) \(\frac{l}{a}=\frac{n+1}{b}=\frac{n}{c}=μ\)
b) \(\frac{l}{a}=\frac{m}{b}=\frac{n}{c}=μ-1\)
c) \(\frac{l}{a}=\frac{m}{c}=\frac{n}{b}=μ\)
d) \(\frac{l}{a}=\frac{n+1}{b}=\frac{n}{c}=μ\)
