Question

Find the missing lengths given: 2) 12 8 ? 7 4) . ? 8 10 27

Answer 1

`\begin{gathered} 2) \\ (x)/(7)=(8)/(4) \\ \\ x=7\cdot((8)/(4)) \\ x=14 \\ \text{The value of the unknown side is 14} \\ \\ 3) \\ (x)/(27-x)=(8)/(10) \\ SOLVING\text{ x} \\ 10x=8\cdot(27-x) \\ 10x=216-8x \\ 10x+8x=216 \\ 18x=216 \\ x=(216)/(18) \\ x=12 \\ \text{The value of the unknown side is 12} \\ \end{gathered}`
