|RZ| = 12cm, |SR| = n, |XZ| = m and SR||YZ. Find m in terms of n
m = 2n
m = 3n
m = 4n
m = 5n
Explanation
\(\frac{n}{4} = \frac{m}{4 + 12}\)
\(\frac{n}{4} = \frac{m}{16}\)
4m = 16n
\(\frac{4m}{4} = \frac{16n}{4}\)
m = 4n
\(\frac{n}{4} = \frac{m}{16}\)
4m = 16n
\(\frac{4m}{4} = \frac{16n}{4}\)
m = 4n
