(10.05 LC) If sin(x) =½
what is cos(x) and tan(x)? Explain your steps in complete sentences. (10 points)

Cos x =

Tan x =

Step-by-step explanation:

Sin x =

So, Perp = 1 and hyp = 2

Putting this in Pythagorean theorem to get the base

base ² = 4-1

base² = 3

Taking square root on both sides

Base =

Now

Cos x =

Tan x =

answer would be 8.64 or s = 11π/4 inches

step-by-step explanation:

s = r θ  

where s = arc length  

r = radius = 3 inches  

θ = central angle in radians = ( π /180)*165  

s = 3(π/180)*165  

= 8.64 inches

hi i’m going tomorrow morning and i can come over and you out with this stuff for me haha ya day is going crazy and i’ll tell you what i’m talking about you don’t wanna go do you think i’m going to be a good friend i just don’t know how much you mean about the stuff you want to do and stuff you know i just want you and you know that i’m going crazy i don’t think i’m going crazy about going tomorrow and i’ll tell ya hey i don’t think i’m going crazy about going tomorrow and i’ll tell you what i’m done
