Answer: 0.023 is twenty-three thousandths written in standard form!
If n is an integer, then cos(n(2<span>π))=1.
Take n=0, cos(2</span>π)=cos(0)=1, n=1, cos(2π)=1, n=2, cos(2(2π))=cos(4<span>π)=cos(0)=1...
If n is not an integer, well, ..... we don't know the value, which depends on the value of n.</span>
Answer:
x = 18.64
Step-by-step explanation:
use tan:
⇒ tan = 
⇒ tan 46 = 
tan of 46 is 1.0355
⇒ 1.0356 = 
multiply 18 on both sides
⇒ 1.0355 x 18 =
x 18
⇒ 18.64 = x
