Answer:
C
Step-by-step explanation:
Sin(12) ≈ 0.208
cos(x) = 0.208
cos(x) = sin(12)
cos(78) = sin(12)
cos(12) ≈ 0.978
cos(68) ≈ 0.375
cos(102) ≈ -0.208
cos(78) ≈ 0.208
The answer is D.
I’m guessing 108. 45 divided by 5 is 9, so 9 times 12 is 108.
When using the Internet to conduct consumer research, be sure to use reliable websites, verify sources and know the purpose. So the answer is letter D. All of these.
