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 =

I think it’s better to be able for the game and it would have been better that it would have a good time and I was not yyyyt it would have to get it bruh bruh is a great day for me and my friends to the world who has no idea who is going on a team is to get a good life
Step one, divide both sides by -2
log8(x+1)=4
if the base is 10, and the 8 is together with (x+1): (cannot tell from the way it is written)
8(x+1)=10^4=10000
x+1=1250
x=1249
if the 8 is a base,
8^4=(x+1)
x+1=4096
x=4095
