The answer is 4260, you can do 200 plus 60, then add to 4000
Let us start subtracting 3 cos theta both sides so that we may get all theta terms on left side only
It is now : 4 cos theta - 3 cos theta = - (sqrt3)/ 2
1 cos theta = -( sqrt 3 ) /2
we know cos (pi-x)= - cos x And cos (pi+ x)= - cos (x)
********* let us first use :
- Cos ( pi - theta) = - ( sqrt 3 )/2
this implies cos (pi- theta )= (sqrt 3) /2
cos ( pi - theta )= cos (pi /6)
pi- theta = pi/6
pi- pi/6 = theta
5 pi/6 = theta
one of teh answer is 5 pi/6 . another value of theta would be :
(2pi - 5pi/6)= 7pi/6
Answer: 5 pi/6 and 7 pi/6
Arcs are just sections of the circle
so lets say you had a pizza
and you put some points on the crust, the legnth of the crust from point to point is that arc
example
if you put poins A and B, then arc AB is the crust between points A and B
arcs can include other points as well
and arc AB=arc BA
so
I wil name easy arcs first
arc AB
arc BC
arc CD
ard DA
now ones that include others
arc AC
arc BD
so the arcs you might want to list are
arc AB
arc BC
arc CD
ard DA
arc AC
arc DB
The answer is 5/6 because you need to flip the numbers.
