When solving for x, the sine of 33º is used. what other angle and trigonometric function could be used to solve for x?
a.
cos 57º
c.
tan 57º
b.
tan 33º
d.
cos 33º

a.

Step-by-step explanation:

We have been given that when solving for x, the sine of 33º is used.

We will use property to solve our given problem.

Upon substituting our given values in above property we will get,

Therefore, could be used to solve for x and option 'a' is the correct choice.

number one is the correct answer

step-by-step explanation: dogs and cats are mentioned, no other animals

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.
