The correct answer is B.
This is because the denominator in this case, would signify be the number of groups.
Answer:

Step-by-step explanation:
From the question we are told that
Six wire are attached to a circuit board
Generally using multiplication rule
Let number of possible sequence be given as S
Mathematically

Therefore
Number of possible sequence 
Hey there :)
Here we need to use Trigonometry!
The given
angle is
61°The
opposite to the angle is
22 So
x is the
adjacent
The trigonometric ratio that uses opposite and adjacent is tan
( I have uploaded a picture to help you )
tan α =

tan 61 =

adj =

adj ≈ 12.19 ≈ 12
x = 12
Since both terms have the same variable to the same power, you can simply add the coefficients...
14x^7
By the Pythagorean theorem, the missing side is -sqrt7. The definition of sin is side opposite over hypotenuse, so go into Q2 and make an angle and label the side opposite the angle with a 3 and the hypotenuse a 4. The other leg is -sqrt7 cuz x is negative in Q2. The cosine of an angle is the side adjacent over the hypotenuse, so the cos then is -sqrt7/4
