The ratios of measures of the angles in triangle abc is 4: 13: 19. find the measures of each of the angles. show all of the work/explain.

Measures of the angles are 20°, 65° and 95°.

Step-by-step explanation:

We are given that,

Ratio of the angles of the triangle ABC is 4 : 13 : 19.

Let the constant corresponding to the measures of the angle = x.

So, the measures of the angles will be,

Since, the sum of measures of the angles of a triangle is 180°.

We get,

i.e.

i.e. x = 5

Thus, the measures of the angles are,

4x = 4×5 = 20°

13x = 13×5 = 65°

19x = 19×5 = 95°

Also, sum of the obtained measures = 20° + 65° + 95° = 180°.

Hence, the measures of the angles are 20°, 65° and 95°.

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.

answer: i realy don't get it that much can you me figer it out pleas you
