In triangle ABC, sin A = 24 25 . Which other expression has a value of 24 25 ? A) sin B B) cos A C) cos B D) tan A
2 answers:
Answer:
Option C). cosB
Step-by-step explanation:
In the picture attached by sin rule sin A = 24/25 means
sin A = BC/AB = 24/25
Now for the same value or same ratio will be of cosine of angle B for which height of the triangle will become base of the triangle.
cos B = BC/AB = 24/25
Therefore option C) cos B is the answer.

Answer:
0.071
Step-by-step explanation:
Number of wins by Alaskan Malamute = 21
Number of win by Great Pyrenees = 3
Number of wins by Siberian Husky = 18
Total number of shows = 42
We need to calculate the empirical probability that next winner will be a Great Pyrenees.
Empirical probability is defined as the ratio of the number of times a specific event occurs to total number of possibilities of all events being considered. In given case, the event that best of the show was a Great Pyrenees occurred 3 times, and total number of events were 42. So,
Empirical Probability that next winner will be a Great Pyrenees =
Hence, the empirical probability that the next winner of "Best of Show" will be a Great Pyrenees is 0.071
