  • A \(\frac{2}{3}\)
  • B \(\frac{3}{5}\)
  • C \(\frac{1}{5}\)
  • D \(\frac{4}{5}\)
Correct Answer: Option C
Explanation:
tan\(\theta\) = \(\frac{3}{4}\)
from Pythagoras tippet, the hypotenus is T
i.e. 3, 4, 5.
then sin \(\theta\) = \(\frac{3}{5}\) and cos\(\theta\) = \(\frac{4}{5}\)
cos\(\theta\) - sin\(\theta\)
\(\frac{4}{5}\) - \(\frac{3}{5}\) = \(\frac{1}{5}\)
