Answer 2

Sorry idk the answer...I actually JUST started trig functions at school yesterday tbh.

Answer 3

That's cool. Thanks for looking though :)

Answer 4

then the angle=pi+0.89
and 2 pi-0.89
because sin is negative in 3rd or 4th quadrant.

Answer 5

I'm very confused. I'm no good at this, sorry :/
