Bcd is a right triangle. the length of the hypotenuse is 22 cm. the length of one of the legs is 18 cm. what is the length of the other leg? enter your answer in the box as a decimal rounded to the nearest tenth. cm

Use (leg)^2 + (leg)^2 = (hyp)^2.

(18)^2 + (leg)^2 = (22)^2

(leg)^2 = 484 - 324

(leg)^2 = 160

Taking the square root on both sides we get leg = sqrt{160}.

The length of the other leg is sqrt{160} cm.

The answer must be given in decimal form.

sqrt{160} = 12.6491106407

We now round to the nearest tenth to find a final answer of 12.60 cm.

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.

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.
