Use the cosine formula
Cos(angle) = adjacent/ hypotenuse
cos(30) = x/8
Cos(30) can be written as sqrt(3)/2
Now you have :
sqrt(3)/2 = x/8
Multiply both sides by 8:
X = sqrt(3)/2 x 8
Simplify:
X = 4sqrt(3)

7$ per bag , I don’t know about can though
Because without place value you might put the decimal in the wrong place and that will effect the answer big time.
Here is what the answer to your question is:
