The exact value of cos120 if the measure 120 degrees intersects the unit circle at point (-1/2,√3/2) is 0.5
<h3>Solving trigonometry identity</h3>
If an angle of measure 120 degrees intersects the unit circle at point (-1/2,√3/2), the measure of cos(120) can be expressed as;
Cos120 = cos(90 + 30)
Using the cosine rule of addition
cos(90 + 30) = cos90cos30 - sin90sin30
cos(90 + 30) = 0(√3/2) - 1(0.5)
cos(90 + 30) = 0 - 0.5
cos(90 + 30) = 0.5
Hence the exact value of cos120 if the measure 120 degrees intersects the unit circle at point (-1/2,√3/2) is 0.5

It’s DG.
A parallel segment to CF is one that will never cross CF and goes in the same direction.
AD is booted because it is going horizontally and not up like CF.
DC is booted also because it is going horizontally and it will cross CF.
AD isn’t the correct answer because it is going horizontally and not in the same direction as CF.
Answer:
--- Two pink and One black
Step-by-step explanation:
Represent the pink skin with P and the black skin with B.
Since black skin is dominant to pink skin, there will be more occurrence of B than P
The punnet square for the breeding of the two pigs is then represented as:
Solving (a): Probability of Pink
In the above square, there is only 1 occurrence of P out of a possible of 4.
So, the probability is:
Solving (b): Probability that first and second are black
In the above square, there is only 3 occurrence of B out of a possible of 4.
So, the probability that both are black is:
Solving (c): Probability of two pink and 1 black
This is calculated as:
X+2x-1+x+5=180
4x+4=180
4x=176
x=44
AEB=44°
the answer is 14
hope this helps have a nice day
