Answer:

-⅗

Step-by-step explanation:

cos 0,6435011088 - 1½π >> ¾

If you are ever in need of assistance, do not hesitate to let me know by subscribing to my You-Tube channel [USERNAME: MATHEMATICS WIZARD], and as always, I am joyous to assist anyone at any time.

**I do not have Unit Circle video uploaded yet, but if I need to, just notify me in the comments or on of course, You-Tube.

*** Plus, we need to make sure that the x-value falls in between 0 and π\2, which it did, so no need to worry.

**** 1½π = 3⁄2π
