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.

.002 is 1/10 of what

amid [387]

Let the unknown number be x. Then (1/10)x = 0.002. To solve for x, multiply both sides by 1000 to remove the decimal fraction 0.002.

Then 1000(1/10)x = 1000(0.002), or 100x = 2. Dividing both sides by x returns

x=100/2, or x= 50 (answer)
