Question

How do you solve `sin40º = 12/y`?

Answer 1

`y~~ 18.6686859223`

Explanation:

You're going to have to use a scientific calculator for this one, since `sin40º` is an irrational number. Here's how I would solve for `y`:

`[1]color(white)(XX)sin40º=12/y`

`[2]color(white)(XX)ysin40º=12`

`[3]color(white)(XX)y=12/(sin40º)`

*Solve using a scientific calculator.

`[4]color(white)(XX)color(red)(y~~ 18.6686859223)`
