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:
slope = -6 and y intercept=0
Step-by-step explanation:
Answer: 90 degrees clockwise
This is equivalent to 270 degrees counterclockwise
The rule for either rotation is 
The x and y coordinates swap places, and the new second coordinate flips from positive to negative (or vice versa).
The diagram below shows an example of this for the point (-4,-2) rotating to (-2, 4). The center of the rotation is the origin (0,0).
Answer:
15.5
Step-by-step explanation:
16.5-10
=15.5
So 15.5 is the range
Multiply the month;y income by the percentage:
8300 x 0.28 = 2324
He can spend $2,324 a month.
