Answer
$ N 15^{\circ} E $
Work Step by Step
The trigonometric ratios are as follows: $\sin \theta= \dfrac{opposite}{hypotenuse}$ ; $\cos \theta= \dfrac{Adjacent}{hypotenuse}$ and $\tan \theta= \dfrac{Opposite}{Adjacent}$
Our equation becomes: $90^{\circ}-75^{\circ}=15^{\circ}$
Our answer is: $ N 15^{\circ} E $
