Answer:None of the given choices
cos θ = sqrt(3) / 2
Explanation:cos 2θ + cos 2θ = 1
2 cos 2θ = 1
cos 2θ = 0.5
Now, to get the value of θ, we would need to use the rules of double the angle attached in the figure.
I will use:
cos 2θ = 2 cos²θ - 1
Substitute with cos 2θ = 0.5 and solve for cos θ as follows:
cos 2θ = 2 cos²θ - 1
0.5 = 2 cos²θ - 1
2cos ²θ = 0.5 + 1 = 3/2
cos²θ = 3/4 = 0.75
cos θ = ±√0.75
Since we are given that θ is acute, therefore, θ belongs to the first quadrant which means that cos θ is positive
Based on the above:
cos θ = √0.75 = √3 / 2
Hope this helps :)
As stated:
x , the first
2x, the second
3x, the third (sum of first two)
x + 2x + 3x = 180°
6x = 180°
x = 30°
Measures of the Angles would be 30°, 60°, 90°

The person will most likely choose a hamster. As you can see 3/13 and 6/13 are equivalent fractions. 6/13 is greater than 3/13 and 6/13 represents the hamsters. There are more hamsters than rabbits so the rabbit will most likely be picked. The probability is 1/2.
