Step 1

1 of 3Transfer the $\tan$ to right side to get the equation in terms of theta,

$\theta=\tan^{-1}(1)$

The range of principal values of $\tan^{-1}$ is $\left[-\dfrac{\pi}{2},\dfrac{\pi}{2}\right]$ so the positive value of $\tan^{-1}$ must be lies between $0$ and $\dfrac{\pi}{2}$.Therefore,

$\theta=45^o$
