Question

give tan(theta) =4/3 and sin(-4/5) find cos(theta)

1/3
-1/3
3/5
-3/5
-sqrt3/5

Answer 1

hint : \(\large \tan \theta = \frac{\sin \theta}{\cos \theta} \)

Answer 2

4/3*-4/5=cosθ

Answer 3

i got 8/15? but i know thats wrong

Answer 4

i got 8/15 wheni tried harsh123 solution and i got no solution for gabeshie8 solution

Answer 5

*ganeshie8

Answer 6

\(\large \tan \theta = \frac{\sin \theta}{\cos \theta}\)


\(\large \frac{4}{3} = \frac{\frac{-4}{5}}{\cos \theta}\)

cross multiply

\(\large 4 \cos \theta= 3\times \frac{-4}{5}\)


divide 4 both sides

\(\large \cos \theta= \frac{-3}{5}\)

Answer 7

oh thankyou
