Question

If tan x° = 11 divided by r and cos x° = r divided by s, what is the value of sin x°?

sin x° = s divided by 11

sin x° = 11 divided by s

sin x° = 11r

sin x° = 11s

Answer 1

hint :

sin x = tan x * cos x

Answer 2

\[\tan x=\frac{ \sin x }{\cos x }=\frac{ 11 }{r },\sin x=\frac{ 11 }{r }*\cos x,\cos x=\frac{ r }{s }\]
find sin x .

Answer 3

Are r and s equal?

Answer 4

\[\sin x=\frac{ 11 }{ r }*\frac{ r }{ s }=?\]
