Trigonometry

Ok then, what do you do?

What are your thoughts?

I typed in sin-1(-0,5243)to get 32
Then subtracted it from 360 to get 328 and i dont know how to find the last nu.ber

I typed in sin-1(-0,5243)to get 32

Why subtracting by 360?

What does the sin graph look like? Can you draw it?

I’ve just done the same and got -32 instead
(also note, it’s probably best to keep to as much accuracy as possible as the decimal place may affect which way to rounding goes at the end)

Ok nice, so what now?

I need the last number

What do you think you can do to get it

It’s not -32 as that’s not in the region of 0, 360

I don't know

That is what the calculator gives and your previous answer wasn't helpful ... yes - 32 isn;t right but an answer in the 4th quadrant is.

I don't know

Your answer 328 was nearly correct [you just rounded 32 too much]- please don't be put off.

Your graph is also correct so you are looking for an angle in the third quadrant - now - what might that be? I also agree that you need to keep at least 1 dp accuracy.

lol how wasn’t my answer helpful?

I’m just trying to help, don’t judge me.
