Question

If tan x°= and cos x°=,what is the value of sin x°?
a. sin x°= y/z
b. sin x°= 10z
c. sin x°= z/y
d. sin x°= 10y

Answer 1

sin x = tan x * cos x

Answer 2

@experimentX explain please

Answer 3

sin x = tan x * cos x
since cos x is the adj/hyp and tan x is the opp/adj, (adj/hyp)*(opp/adj) = opp/hyp, right? Now Opp/hyp = sin x, so that means that cos x * tan x = sin x

Answer 4

tan x = sin x / cos x

Answer 5

and your values are also missing ... but if you have values you can use this relation to calculate the value of sin x

Answer 6

thanx guys!
