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:
To verify the identity:
sinx/1-cosx = cscx + cotx
we will follow the steps below;
We will take just the left-hand side and work it out to see if it is equal to the right-hand side
sinx/1-cosx
Multiply the numerator and denominator by 1 + cosx
That is;
= 
open the parenthesis on the right-hand side of the equation at the numerator and the denominator
sinx(1+cosx) = sinx + sinx cosx
(1-cosx)(1+cosx) = 1 - cos²x
Hence
= 
But 1- cos²x = sin²x
Hence we will replace 1- cos²x by sin²x
