Remember that cos is just a translation of sin and vice versa.
So:
Sin(x) = Cos(90 - x)
Cos(x) = Sin(90 - x)
Therefore, to answer your question:
Cos(19) = Sin(90 - 19)
= Sin(71)
a repeating decimal is placed over 9's instead of 0's. for example: 0.23 = 
, but 0.232323... = 
a) x = 0.121212
b) 100(x) = 100(0.121212)
100x = 12.1212
c) 100x = 12.1212
- <u> x = 0.1212</u>
99x = 12
x = 
d) -2 <em>= -2
when simplified</em>
The number is rational becase it has a repeating decimal
The correct answer is: [B]: "False" .

Answer:
-6<x<-9
Step-by-step explanation:
if x+9<0 and 2x>-12
x<-9
x>-6
X is smaller than -9 but greater than -6.
The solution is -6<x<-9
Answer:
x=3
y=6
