If cosθ=−1/2 and sinθ=3√/2, what must be the value of θ? 120°

150°

210°

300°

330°

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)

answer: c

(2, -4)

goes 7 to the

(9, 4)
