Eduardo and paul are leaving the same airport in florida. eduardo’s flight to jamaica is 273 miles long. paul's flight to honduras is 357 miles long. if their destinations are 238 miles apart, what is the angle formed by their flight paths? round the answer to the nearest tenth. a. 40.9° b. 41.8° c. 43.8° d. 52.6°

B. 41.8° is the correct answer

Step-by-step explanation:

We are given that,

Length of Eduardo's flight path = 273 miles

Length of Paul's flight path = 357 miles

Distance between their destinations = 238 miles.

Now, using the law of cosines, we get,

i.e.

i.e.

i.e.

i.e.

i.e.

i.e.  θ = 41.8°

Hence, the angle between their flight paths is 41.8°.

introduction, methodology, results, discussion

step-by-step explanation:

an observational study is one which consists of actual observation to record data and then analyse the data.

there are a number of factors that should be analyzed before starting an observational study.

the main four factors are:

i) introduction:   this should be analysed to check whether the purpose of the study is correctly established and the data recorded are appropriate for the study

methodology:   the method of collecting the data, such as whether randomly selected, and whether sample size matches with the population to be studied, whether questions asked are easy to answer by common men, etc.

results: then results such as summary of data with comments should be studied thoroughly

discussion:   the last is the discussion, this can be either by management people or persons who are all interested , etc.

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.
