Answer 1

to find the coordinates you'll need the cos and sin of the angle its just like with x and y:

(x,y)= (cos angle, sin angle)

to find the sin, you simply need to use these formulas:

sin² A + cos ² A= 1

sin A/ cos A= tan A

1.

sin² O + cos² O= 1

sin²O= 1- cos² O

sin²O= 1- (-9/41)²

sin²O= 1600/1681

sin O= V1600/ V1681

sin O= 40/41

2.

sin O/ cos O = tan O

(40/41)/(-9/41)= tan O

-164/9= tan O
