We know that the law of sines states that:

For simplicity, let:

In triangle A1BC this leads to:

Therefore:

Now, triangle A2BC is isosceles which means that both the base angles are equal, since angle CA1B and A2A1B are supplementary we have:
Answer:
The answer is A.
Step-by-step explanation:
(0,2) represents the y intercept on the graph cause at that point it crosses the y axis
Answer:
0.64 is the proportion of students in the population who failed to notice the woman in the gorilla suit
Step-by-step explanation:
We are given the following in the question:
Total number of students, n = 25
Number of student who noticed woman in gorilla suit = 9
Number of student who failed to notice woman in gorilla suit, x = 25 - 9 = 16
We have to find the proportion of the students in the population who failed to notice the woman in the gorilla suit.
Formula:

0.64 is the proportion of students in the population who failed to notice the woman in the gorilla suit
