i use the quadratic formula and i have 3 out of 4 answers. thisis my answer theta = 83.23,305.07 and 263.23. (there are in degrees) that all i got. what the 4th solution?

when u got 83.23, you add 180 to get 263.23 when u get 305.07, you subtract 180 to get 305.07180 =... ? because, the tan is periodic with 180 degrees, that is the value of tan repeats after every 180 degrees.

becuase tan can only be in the 3rd and the 1st. what i meant to say is that 120 degrees is at the 2nd quad. how is tan is postive?

you got 2 roots, right ? one positive > 1st and 3rd Quad one negative >2nd and 4th quad.
