The number of ways can 8 people be seated in a circle if 3 people insist on sitting next to each other is 56 ways.
<h3>How to illustrate the information?</h3>
Combinations are also referred to as selections. Combinations implies the selection of things from a given set of things. In this case, we intend to select the objects.
Combination formula
nCr = n! / ((n – r)! r!)
n = the number of items.
r = how many items are taken at a time.
This will be:
= 8! / (8 - 3!) 3!
= 8! / 5! 3!
= 8 × 7 × 6 / 3 × 2
= 5
There can be 56 ways.

Answer:
x = 65
Step-by-step explanation:
Csc a - sin a = cos a cot a
1/sin a - sin a = cos a (cos a / sin a)
(1 - sin^2 a)/sin a = cos^2 a/sin a
cos^2 a/sin a = cos^2 a/sin a
Therefore, the given equation is an identity.
O+o+2>36
2o>34
o>17
o1>17
o2>19
o is equal to odd number
