Question

Find the value of tan theta if cos theta equal 3/5

Answer 1

4/3

Explanation:

$\cos( \theta)= \frac{3}{5} \\ \sin( \theta) = \sqrt{1 - \frac{3 {}^{2} }{5 {}^{2} } } = \frac{4}{5} \\ \tan( \theta) = \frac{ \sin( \theta) }{ \cos( \theta) } = \frac{ \frac{4}{5} }{ \frac{3}{5} } = \frac{4}{3}$
