2. from the top of a vertical cliff 40 m high, the object is 59.3m from the base of the cliff. find the angle of depression to the objeci. a) 34° b ) 940 c ) 104 degrees d) 540

is the angle of depression from the vertical cliff.

Option: A

Step-by-step explanation:

Given that, Height of the cliff (opposite side) = 40m

Distance of object from the base of the cliff (adjecent side)  = 59.3m

To find the angle of depression of the object. From trigonometric rule in a right angled triangle, we know that Angle of depression = Therefore, the angle of depression to the object is .

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.
