Answer:
Step-by-step explanation:
We can first solve for the face diagonal. That is . Notice this will form a right triangle with the vertical side. We get that the face diagonal = . Now, we can use Pythagorean theorem again to get the straw length:
where s = the straw length.
We can solve that s =
wearing because of the division of running man.
Step-by-step explanation:
The statistics are divided by 29 to get the answer in cubic cm.
It would be $7.50 because 4 ounces equals $1 so 30/4 =7.5
Answer:
In the explanation
Step-by-step explanation:
Going to start with the sum identities
sin(x+y)=sin(x)cos(y)+sin(y)cos(x)
cos(x+y)=cos(x)cos(y)-sin(x)sin(y)
sin(x)cos(x+y)=sin(x)cos(x)cos(y)-sin(x)sin(x)sin(y)
cos(x)sin(x+y)=cos(x)sin(x)cos(y)+cos(x)sin(y)cos(x)
Now we are going to take the line there and subtract the line before it from it.
I do also notice that column 1 have cos(y)cos(x)sin(x) in common while column 2 has sin(y) in common.
cos(x)sin(x+y)-sin(x)cos(x+y)
=0+sin(y)[cos^2(x)+sin^2(x)]
=sin(y)(1)
=sin(y)
