Which equation is correct?

triangle acb, angle c is a right angle, angle b measures g degrees, angle a measures h degrees, segment ac measures x, segment cb measures y, and segment ab measures z

sin h° = y ÷ x
sin h° = x ÷ y
tan h° = y ÷ x
tan h° = x ÷ y

The correct equation is sin h° = y ÷ x.

We have to determine, the correct statement equation for the given condition.

According to the question,

Triangle ACB, angle C is a right angle,

Angle B measures g degrees, angle A measures h degrees,

Segment AC measures x, segment CB measures y, and segment AB measures z.

Therefore,

Sine is the ratio of the length of the side that is opposite that angle to the length of the longest side of the triangle (the hypotenuse).

Then, In Triangle ACB, angle C is a right angle,

And segment AC measures x, segment CB measures y,

And,

The tangent of an angle is the trigonometric ratio between the adjacent side and the opposite side of a right triangle containing that angle.

Segment CB measures y, and

Segment AB measures z.

Hence, The correct statement is sin h° = y ÷ x.

The answer is probably sin h°= y÷x. This is because of the angles if C is a right triangle then BA cannot be x÷y. Then, if the answer is tan then it will not make a triangle.

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.
