The solution to the question is:
c is 6 = 
b is 5 = 
cosB is 2 = 
a is 4 = 
cosA is 3 = 
cosC is 1 = 
<h3>What is cosine rule?</h3>
it is used to relate the three sides of a triangle with the angle facing one of its sides.
The square of the side facing the included angle is equal to the some of the squares of the other sides and the product of twice the other two sides and the cosine of the included angle.
Analysis:
If c is the side facing the included angle C, then
=
+
-2ab cos C-----------------1
then c = 
if b is the side facing the included angle B, then
=
+
-2accosB-----------------2
b = 
from equation 2, make cosB the subject of equation
2ac cosB =
+
- 
cosB = 
if a is the side facing the included angle A, then
=
+
-2bccosA--------------------3
a = 
from equation 3, making cosA subject of the equation
2bcosA =
+
- 
cosA = 
from equation 1, making cos C the subject
2abcosC =
+
- 
cos C = 
In conclusion,
c is 6 = 
b is 5 = 
cosB is 2 = 
a is 4 = 
cosA is 3 = 
cosC is 1 =

Step-by-step explanation:
Answer:
165
Step-by-step explanation:
How many complete vases can Cameron's Flower shop fill with 8 flowers each, considering they have a total of 1,323 flowers in total.
All you have to do is divide 1,323 by 8 to get = 165.375 or 165 and 3/8.
Since the question is about COMPLETE vases of 8 flowers, that means the answer is 165, and we don't count the 3 remaining flowers.
Good job Cameron!
Answer:
76 ounces
Step-by-step explanation:
I'm assuming you meant:
5lb+7oz-11oz=
16 ounces in a pound
5lb+7oz-11oz=
80+7-11=
87-11=
76 ounces
