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 help you solve, including the variables and measurements you assigned to each side and angle. Round your answer to the nearest foot.

We have been given the angle (40°), the hypotenuse (100 ft), and we are being asked for the height (h) above the ground. Using the triangle formed, the appropriate trig ratio is sine because sin(θ) = opposite/hypotenuse where θ = 40°, the hypotenuse = 100, and the opposite = h. So:

sin(40°) = h/100

Multiplying both sides by 100 gives:

h = 100•sin(40°)

h = 100•(0.6427876)

h = 64 feet

The kite string, the ground, and the height make a right triangle. The kite string is the hypotenuse, 80 meters. The angle between the ground and kite string is 40º.

sin40º = height/80

height = 80sin40º

height ≈ 51.423 meters

Step-by-step explanation:

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.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
