Alright, lets get started.

Please take a look at the diagram attached.

The reference angle of 75 will be 75

As it is mentioned that the angle intersects the unit circle means r = 1

So, finding cos

cos 75 = $\frac{X}{r}$

cos 75 = $\frac{0.259}{1}$

cos 75 = 0.259 : Answer

Hope it will help :)
