Question

if tan theta is equals to - 4 by 3 then sin theta is​

Answer 1

Hope u understood it

Answer 2

In triangle ABC,

Let AC be hypotenuse,

AB altitude and BC base.

Then tanC=4/3

Opposite side/adjacent side

AB/BC=4/3

AB=4

BC=3

AC=√(AB^2+BC^2)

AC=√25=5

SinC=opposite side /hypotenuse

=AB/AC

=4/5

Hope it helps.....
