Question

Find the missing side length. Assume that all intersecting sides meet at right angles. Be sure to include the correct unit in your answer. 7 yd 8 yd 13 yd 9 yd 16 yd?

Answer 1

Let:

x = missing side length

`\begin{gathered} x=13yd-8yd \\ x=5yd \end{gathered}`

-------------------------

Let:

y = missing side length:

`\begin{gathered} y+7yd=16yd \\ \text{solving for y:} \\ y=16yd-7yd \\ y=9yd \end{gathered}`
