Quinn is flying a kite. the angle of elevation formed by the kite string and the ground is 40° and the kite string forms a straight segment that is 100 feet long
explain how to find the distance between the ground and the kite. include a description of the triangle you drew to you solve. including the variables and measurements you assigned to each side and angle. round your answer to the nearest foot.

answer:

step-by-step explanation:

this is right triangle trig.   therefore, the shape that is formed from this situation is a right triangle.   the hypotenuse is the kite string (100 feet), the base angle that is not the right angle is the angle of elevation (40 degrees), and we are looking for the height of the triangle.   it just so happens that the height of the triangle is the side opposite the angle of elevation.   therefore, we can use the sin ratio to find the height that the kite is from the ground.

if we fill in our values:

where x is the height of the triangle (also the distance that the kite is from the ground).

solving for x:

100 sin(40) = x

plug this into your calculator in degree mode and get that

x = 64.2 so 64 feet, rounded to the nearest foot

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.
