Question

I’m stuck on this question. any help would be greatly appreciated

Answer 1

Using the Pythagorean theorem we get:

`y^2+8^2=12^2.`

Simplifying the above result we get:

`y^2+64=144.`

Subtracting 64 from the above equation we get:

`\begin{gathered} y^2+64-64=144-64, \\ y^2=80. \end{gathered}`

Therefore:

`y=√(80)\approx8.9.`

Answer:

`y=8.9.`
