In △abc, m∠a=32°, m∠b=25°, and a=18. find c to the nearest tenth.

28.5

Step-by-step explanation:

We have been given that in △ABC, m∠A=32°, m∠B=25°, and a=18.  We are asked to find the value of c to nearest tenth.

We will use law of sines to solve our given problem.

, where a, b and c are opposite sides to angle A, B and C.

First of all, we will find measure of angle C using angle sum property.

Substituting our values in law of sines, we will get:

Switch sides:

Therefore, the value of c is 28.5 to the nearest tenth.

jacob, non hispanic white male. 30 years old.

probability that jacob lives to be 30 years old. 

since the given probabilities are probabilities of dying, i think we simply subtract it from 1 to get the probability of living. we will use the probability of non hispanic white male.

                                          probability of living to be 30 y.o.

29 - 30 : 1 - 0.001477 = 0.998523

30 - 31 : 1 - 0.001503 = 0.998497
