One side of a triangle is one-fourth the longest side. The third side is 8 feet less than the longest side. The perimeter is
118. Find all three sides.

The sides have lengths of , , and feet.

Step-by-step explanation:

Let's call A the longest side. The others triangle sides are B and C.

We know that B = (1/4)*A  and C = A - 8

The triangle's perimeter is: A + B + C = 118

Substituting the values of sides B and C, we have:

A + (1/4)A + (A-8) = 118

Adding common terms:   (2 + 1/4)A = 118 + 8

                                     (9/4)A = 126    then,  A = 56 feet

                                     B = (1/4)A = 14 ft

                                     C = A - 8 = 48 feet

I hope it works for you

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.
