Question

If sin o= 5/13, find cos o​

Answer 1

Step-by-step explanation:

U can use right angle triangle

or by formula

$\cos(x) = \sqrt{1 - { \sin^{2}(x) } } \\ \cos(x) = \sqrt{1 - ( \frac{ {5}^{2} }{ {13}^{2} }) } \\ = \sqrt{ 1 - \frac{25}{169} } \\ = \sqrt{ \frac{169 - 25}{169} } \\ = \sqrt{ \frac{144}{25} } \\ = \frac{12}{25} ...ans$

Answer 2

Answer:

ok I'm taking o as theta

hope this helps!
