Question

Find the length of the missing side of a triangle. 85in 84in what's the length of the missing side

Answer 1

13 in

Step-by-step explanation

let's use the Pythagoras theorem

`\text{side}^2+side^2=hyp^2`

then, let

adjancent side=side1=84 in

opposite side= y

hypotenuse=85 in

now, replace

`\begin{gathered} 84^2+y^2=85^2 \\ 7056+y^2=7225 \\ \text{subtract 7056 in both sides} \\ 7056+y^2-7056=7225-7056 \\ y^2=169 \\ \sqrt[]{y}=\sqrt[]{169} \\ y=13 \end{gathered}`

so, the missing side is 13 in.

I hope this helps you
