If cosΘ = -1/2, what does theta equal? There are two answers, put the smaller answer first (a)   and ​ (b)  

• 240

• 330

• 45

• 60

• 360

• 120

• 135

• 345

• 210

• 225

Answer explanation

cosine correlates with x values and there are only two points on the unit circle with an x value of -1/2 and they are 240 and 120
