You have to use the Law of Cosines twice here. Let's find angle A first:
. Doing a bit of simplifying you get
. Simplifying a bit more gives you -544=-696cosA. cosA = .78160919 and that A = 38.6. Actually, now that I think about it we can now move to the Law of Sines to find another angle because the triangle is not a right triangle. Just trust me. Let's find angle B now.
and that
. sinB = .3565026267 and that angle B is 20.9. Knowing those 2 angles we can find C: 180-38.6-20.9=120.5 and there you have it.
Answer:
37.27% probability that he or she will have a heart attack.
Step-by-step explanation:
Bayes Theorem:
Two events, A and B.
In which P(B|A) is the probability of B happening when A has happened and P(A|B) is the probability of A happening when B has happened.
In this question:
Event A: Periodontal disease
Event B: Heart attack
Researchers discovered that 82% of people who have suffered a heart attack had periodontal disease, an inflammation of the gums.
This means that
Only 33% of healthy people have this disease.
This means that
Suppose that in a certain community heart attacks are quite rare, occurring with only 15% probability.
This means that
If someone has periodontal disease, what is the probability that he or she will have a heart attack
37.27% probability that he or she will have a heart attack.
