Answer 2

@grex10 try to use that tan(x)=sin(x)/cos(x)

Answer 3

i got c using tan x = sin x/ cos x

Answer 4

\[\sin(x)=\cos(x) \tan(x)\]

Answer 5

now replace cos(x) with 10/y and tan(x) with z/10

Answer 6

I just took tan(x)=sin(x)/cos(x) and multiply both sides by cos(x) to get that identity above I'm using

Answer 7

so the answer is sin x = y/z?
