Answer:
-0.2
Step-by-step explanation:
Sine and cosine are co-functions.
That means, cos(90-x)=sin(x) or sin(90-x)=cos(x).
So here since cos(90-x)=-0.2, then sin(x)=-0.2.
For lines to be parallel they must have the same slope. If:
y=mx+b
For any line to be parallel to the above it must also have the same value for m in that line.
Answer:
A =12.56 miles^2
Step-by-step explanation:
The area of a circle is
A = pi r^2
A = 3.14 (2)^2
A = 3.14 (4)
A =12.56 miles^2
A. if the return trip is the same then the bird traveled 40miles
