Given the values of the three sides of the triangle, we can apply the Cosine Law to find the angles of the triangle. Recall that for we can express the value of c through the equation below.
Rearranging this equation, we can find the value ∠C as shown below.
We can apply the same reasoning for finding the value of ∠B as shown.
Plugging in the values of the sides (see image attached) from the given. It will now be straightforward to compute for ∠B and ∠C.
Answer: ∠C = 37.19° and ∠B = 53.13°

Answer:
0.3907
Step-by-step explanation:
We are given that 36% of adults questioned reported that their health was excellent.
Probability of good health = 0.36
Among 11 adults randomly selected from this area, only 3 reported that their health was excellent.
Now we are supposed to find the probability that when 11 adults are randomly selected, 3 or fewer are in excellent health.
i.e.
Formula :
p is the probability of success i.e. p = 0.36
q = probability of failure = 1- 0.36 = 0.64
n = 11
So,
Hence the probability that when 11 adults are randomly selected, 3 or fewer are in excellent health is 0.3907
