Question

if sin thita = 11/61 then find cos thita and tan thita​

Answer 1

Answer:

60/61

11/60

Step-by-step explanation:

cos theta = 60/61

tan theta = 11/60

Answer 2

Answer:

$\sin( \alpha ) = \frac{11}{61} \\ \cos( \alpha ) = \sqrt{1 - { \ \sin ^{2}( \alpha ) } } = \sqrt{1 - { \frac{(11}{61} })^{2} } \\ = \sqrt{ \frac{ {61}^{2} - {11}^{2} }{ {61}^{2} } } \\ = \sqrt{ \frac{3721 - 121}{ {61}^{2} } } \\ = \sqrt{ \frac{3600}{ {61}^{2} } } \\ = \frac{60}{61}$

$\tan( \alpha ) = \frac{ \sin( \alpha ) }{ \cos( \alpha ) } \\ = \frac{ \frac{11}{61} }{ \frac{60}{61} } \\ = \frac{11}{60}$
