Answer: 44.4

Step-by-step explanation:

We are asked to find angle V, so we are going to use our trig ratios to explain this one. They have given us the side opposite of angle v and the hypotunse. angle v. so we are going to be using sine. . SOHCAHTOA.

First, let use the ratio for sine $\frac{opp}{hypo\\}$ which equal to $\frac{7}{10}$

then we are to take the arcsine or the sine inverse because we are trying to the angle measure not side length. ( $sin^{-1}$ (7/10) which gives us 44.4

Answer:

The answer is "5, 12, and 13".

Step-by-step explanation:

Please find the complete question in the attached file.

The right triangle is a triangle with only an angle of 90 degrees, as well as the go in the angle of 90 degrees, which is considered a hypotenuse.

The hypotenuse calculation square is equivalent to both the squared measures of the other two sides:

$C^2=A^2+B^2$

And even those squares do verify the equation:

$169 = 144 + 25$

So, it's a rectangular (right) triangle, with sides spanning $5, 12, \ and \ 13.$

What is the value of y in the equation 3(3y − 12) = 0? 4 5 6 9

tatuchka [14]

The equation that is given in the question is:
3 (3y - 12) = 0
9y - 36 = 0
9y = 36
y = 36/9
= 4
The value of y in the equation is 4. The correct option among all the options that are given in the question is the first option.

Classify each description as either an observational study or an experiment.

Eva8 [605]

Answer:

1. Experiment

2. Observation study

3. Experiment

4. Observation study

5. Experiment

Step-by-step explanation:

Observational study Vs. Experiment

An observational study is a study where researchers simply collect data based on what is observed and give results based on the data collected.
There is no control over the variables in an observational study.
An experiment is a method of applying treatments to a group and recording the effects.
The variables in a an experiment can be controlled.
An observational study is where nothing changes but in an experimental study we have control over groups and may change.

1. This is an experiment as people were divided into groups and treatment were given.

2. This is an observational study as no treatment was done on the people just political preference was measured on the basis of collected data.

3. This is an experiment as farmers were divided into groups and effects of a new pesticide was tested.

4. This is an observational study as the data collected told about effect of exercise on lowering the risk of cancer and no experiments were carried out.

5. This is an experiment as people were divided into groups and cholesterol was measured with and without exercise.
