Question

Tan x is ........ Cos x is ........ Sin x is ..........

Answer 1

tan(x)=0.75 sin(x)=0.6 Cos(x)=0.8

Explanation:

`tan(x)=(opposite)/(adjacent)=(3)/(4)=0.75`

`cos(x)=(adjacent)/(hypotenuse)= (4)/(5) =0.8`

`sin(x)=(opposite)/(hypotenuse)=(3)/(5)=0.6`

opposite=3

adjacent=4

hypotenuse=5

try remembering it as SOH CAH TOA

Answer 2

Tan x= 3/4 Cos x= 4/5 Sin x=3/5

Explanation:

"soh-cah-toa"

Just an easy way to remember how Sine, Cosine and Tangent work:

Soh...

Sine = Opposite / Hypotenuse

...cah...

Cosine = Adjacent / Hypotenuse

...toa

Tangent = Opposite / Adjacent
