Question #40d8c

Answer 1

`theta=13` degrees, `193` degrees (assuming that your domain is `0<=theta<360`)

General equation: `theta=180n+13`, where `n` is an integer.

Explanation:

Here is your equation:
`(tan(theta-13))/2=0`

If we multiply by 2 on each side:

`tan(theta-13)=0`

Now, let's set `a=theta-13`. So:

`tan(a)=0`

`a=0` degrees, `180` degrees

Therefore:

`theta-13=0` and `theta-13=180`

`theta=13` degrees, `193` degrees (assuming that your domain is `0<=theta<360`)

Here is the general equation for answers to this equation:

`theta=180n+13`, where `n` is an integer.

This means that, if you substitute `n` for any integer (negative, zero, or positive), the value you get will satisfy the equation. Hope this helps!
