Answer 1

Given: The image shown

To Determine: The value of the unknown

Solution

Let us apply the pytahgoras theorem

From the right triangle ABD

`\begin{gathered} hypothenuse)^2=leg1^2+leg2^2 \\ ?^2=4^2+4^2 \\ ?^2=16+16 \\ ?^2=32 \\ ?=√(32) \\ ?=4√(2)inches \end{gathered}`

Hence, the unknown side is 4√2 inches
