Question

3
If sin =
find cos O and tan 0.
5​

Answer 1

Answer:

$cos0 = \frac{4}{5}$

tan0 = $\frac{3}{4}$

Step-by-step explanation:

I can't understand the question.

But, According to me,

        $sin0 = \frac{3}{5}$

According to formula,

    $cos0 = \frac{\sqrt{(5^{2}-3^{2} )} }{5}$

=> $cos0 = \frac{\sqrt{25-9}}{5}$

=> $cos0 = \frac{\sqrt{16} }{5}$

=> $cos0 = \frac{4}{5}$

 ∴ tan0 = $\frac{sin0}{cos0}$

=>  $tan0 =\frac{\frac{3}{5} }{\frac{4}{5} }$

=> tan0 = $\frac{3}{4}$
