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)
Answer: I believe it is "It also has a reflectional symmetry
Step-by-step explanation: Because even if you rotate the picture if you fold it in half it will fit perfectly with each other
Step-by-step explanation:
x² + 3x + 2
x² + x + 2x + 2 because 1+2=3 and 2×1=2
By taking out common terms, we get
x(x+1)+2(x+1)
(x+1)(x+2)
It is a mixed number because 12/2 can be written as 6 instead of 12/2
