Answer 1

Just substitute x=\(\sf sin\theta\)

And then factor that equation.

Answer 2

After factoring is where I need the help.

Answer 3

And once you have it factored, you just replace x with \(\sf sin\theta\) and just solve for \(\theta\)

Answer 4

So that equation can be factored to:
\(\sf (4x+1)^2=0\)

Answer 5

sin=-1/4

Answer 6

So you basically solve:
\(\sf 4sin\theta +1 - 0\)

Answer 7

Exactly!

Answer 8

I know the algebra; Help me from after this.

Answer 9

And then you have to use a calculator to solve for it since it does not have any special angles.

Answer 10

I am getting 14.4

Answer 11

Oh I already got this right. The system is just picky.

but 14.4 isn't close

Answer 12

i did it right earlier. what am i doing wrong now?

Answer 13

oh NEGATIVE 1/4

Answer 14

Exactly, and also remember we are in degrees.

Answer 15

So when you put in -1/4 you get -14.48

Answer 16

-14.5+360=345.5
and 180-(-14.5)=194.4

Answer 17

Exactly :)
