use the calculator to find theta with a line threw it to the nearest tenth of a degree if theta degree<0 with a line thre it <360 degree sin 0 with a line threw it =negaive 1/2

This just makes no sense to me, sorry.

I agree with bob

Just gotta love those guys throwing lines at theta.

I will take a wild guess that you meant

find Ø where sin Ø = -1/2 , 0° < Ø < 360°

so Ø must be in quadrants III or IV

we know sin 30° = +1/2

so Ø = 180+30 or 210°

or Ø = 360-30 or 330°

(to the nearest tenth, Ø = 210.0 or 330.0° )
