From the diagram above. Find the fraction of the shaded position?
  • A.
    (frac{1}{3})
  • B.
    (frac{1}{5})
  • C.
    (frac{1}{4})
  • D.
    (frac{1}{6})
Correct Answer: Option D
Explanation

(theta) = 180o -(90 + 60)
(theta) = 180o – 150o = 30o
Fraction of shaded position = (frac{30}{360}) + (frac{30}{360})
= (frac{1}{12}) + (frac{1}{12}) = (frac{1}{6})
