Question

Please help me with this trigonometry math question ASAP! Thanks so much!

Answer 1

`cos\alpha =(7)/(25); \ tan\alpha =-(7)/(24).`

Explanation:

if π<α<2π and cotα<0, then 1.5π<α<2π. It means, that cosα>0 and tanα<0.

1) tanα=1/cotα; ⇒tanα= -7/24;

2)
`cos\alpha =(1)/(√(1+cot^2\alpha ))}; \ cos\alpha =(7)/(25).`
