Question

Solve for 0 less than or equal to x less than 360.
4 sinx=-2

Answer 1

divide both sides by 4

sin(x) = -1/2

so the angles are in the 3rd and 4th quadrants.

so find \[x = \sin^{-1}(\frac{1}{2})\]

then the angle measures will be

3rd quadrant (180 + x)

4th quadrant (360 - x)

hope this helps.

Answer 2

yes it does! Thank you so much!
