12.7
Using the Pythagorean theorem, you can easily calculate the length of BC.
So:
BC = sqrt(12^2 - 6^2) = sqrt(144 - 36) = sqrt(108) = 10.39230485
Now consider triangle BCD. You know all three angles and one side. Using the law of sines you know that ratio of the sine of each angle over the opposite side is constant. So:
BC/sin(55) = CD/sin(90)
BC/sin(55) = CD/sin(90)
sin(90)BC/sin(55) = CD
1*BC/sin(55) = CD
BC/sin(55) = CD
10.39230485/0.819152044 = CD
12.68666167 = CD
12.7 = CD
Answer: It would be E
Step-by-step explanation:
S + 2l = 1372
s + l =858
s + 2l = 1372
-s - l =. - 858
l= 514 grams a large bottle
s + 514= 858
s = 344 grams a small bottle
(b) , because if you expand 3(n+6), it is
(3×n)+(3×6) = 3n+18
hope this helps! :)))
