Rewrite <span>2cos x + 1 = 0 as:
2 cos x = -1, and then cos x = -1/2
x must be in Quadrant II or Quadrant III, since the adj. side is negative.
Note that the angle 120 has adj. side -1 and hyp 2. So 120 degrees is one solution.
Now what about a possible 2nd solution, to be found in Quadrant III? That would be -120 degrees, which has the same terminal line as does 240 degrees.
No soap.
So, the solution is 120 degrees.</span>

Answer:
0.24
Step-by-step explanation:
Probability is the ratio of the number of possible outcome to the number of total outcome. The probability that an even will happen or not happen is 1.
Given that the spun has 10 sections 3 red, 3 blue and 4 green, the probability of not getting green
= (3 + 3)/(3 + 3 + 4)
= 6/10
The probability of getting green
= 4/10
Hence the probability of getting not green then green
= 6/10 * 4/10
= 24/100
= 0.24
The nearest to the ten thousand is 20,000.
