Question

If tanx = 5/12
and sinx is negative, find cosx.
​

Answer 1

Hey brainly user

Here is your answer

$\tan(x) = \frac{5}{12}$

$c {}^{2} = a {}^{2} + b {}^{2}$

$c {}^{2} = 5 {}^{2} + 12 {}^{2}$

$c = 13$

$\cos(x) = \frac{adj}{hyp}$

$\cos(x) = \frac{12}{13}$

Answer 2

Answer:

tanx=5/2=P/b

Step-by-step explanation:

h=

$\ \sqrt{ {12}^{2} } - \sqrt{5 {}^{2} } = \sqrt{119}$

=13

so,cosx=12/13
