Answer:
cos2θ = -0.7041
Cos θ = -0.3847
Step-by-step explanation:
Firstly, we should understand that since θ is in quadrant 2, the value of our cosine will be negative. Only the sine is positive in quadrant 2.
Now the sine of an angle refers to the ratio of the opposite to the adjacent. And since there are three sides to a triangle, we need to find the third side which is the adjacent so that we will be able to evaluate the cosine of the angle.
What to use here is the Pythagoras’ theorem which states that the square of the hypotenuse is equal to the sum of the squares of the adjacent and the opposite.
Since Sine = opposite/hypotenuse, this means that the opposite is 12 and the hypnotist 13
Thus the adjacent let’s say d can be calculated as follows
13^2 = 12^2 + d^2
169 = 144 + d^2
d^2 = 169-144
d^2 = 25
d = √25 = ±5
Since we are on the second quadrant, the value of our adjacent is -5 since the x-coordinate on the second quadrant is negative.(negative x - axis)
The value of cos θ = Adjacent/hypotenuse = -5/13
Cos θ = -5/13
Cos θ = -0.3846
Using trigonometric formulas;
Cos 2θ = cos (θ + θ) = cos θ cos θ - sin θ sin
θ = cos^2 θ - sin^2 θ
Cos 2θ = (-5/13)^2 - (12/13)^2
Cos 2θ = 25/169 - 144/169
Cos 2θ = (25-144)/169 = -119/169
Cos 2θ = -0.7041
Answer:C 4:6
Step-by-step explanation:
1. Books goes first so in this case it 4
2. Tennis is 6 sorry it 4:6

The ratio of the frequency of a prime rolled using the first two (ordinary)dice to the frequency of a prime rolled using the unusual die and one ordinary die is
<h3>The Cases and there Probable Results</h3>
There are a total of 36 equally probable ways the dice can fall
In the first case, primes are achieved for the following results:
- 2 (one way possible),
- 3 (two ways possible),
- 5 (4 ways possible),
- 7 (six ways possible), and
- 11 (2 ways possible.
So primes are achieved in a total of 15 ways.
In the second case, the prime possibilities are
- 3 (one way possible),
- 5 (two ways),
- 7 (3 ways),
- 11 (3 ways),
- 13 (3 ways), and
- 17 (just one way).
The total is 13 ways.
