Question

How do you solve `tan(16)=3/x`?

Answer 1

The answer, of course, depends upon whether the `16` is `16^@` or `16 " radians"`

The methodology is the same so I will assume `16^@`

`tan(16^@) = 0.286745` `color(white)("XXXX")`using a calculator

So
`color(white)("XXXX")` `0.286745 = 3/x`

`color(white)("XXXX")` `x = 3/0.286745 = 10.46224`
