What angle measure is complimentary to a 37 degree angle

53 degree angle

Step-by-step explanation:

Two angles are said to be complementary if they add up to 90 degrees. Let the complementary angle of 37 degrees is x. These two angles must add up to 90 degrees. So we can set up the equation as:

37 + x  = 90

Subtracting 37 from both sides, we get:

x = 90 - 37

x = 53 degree angle

From the above solution we can see that if we want to find the complementary angle of any angle, we can subtract the given measure from 90 degrees to get our answer.

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.
