Answer:

As a rule of thumb, if you know only the two shorter side, their ratio is the tangent of the angle opposed to the side you use as a numerator.

If you know one side and the hypotenuse, the ratio side/hypotenuse is either the sine of the opposite angle, or the cosine of the adjacent angle.

taurus [48]

Answer:

The options are absent, but the dependent variable in this experimental setup is the test scores from both groups of the experiment.

Step-by-step explanation:

The dependent variable, just like the name suggests, is the variable whose value or outcome depends on the some other variable(s) in an experimental setup.

For this research study, the aim is to evaluate the effect of a silent studying environment or listening to classical music while studying on the academic performance of students as reflected in their test scores.

So, for each of the two groups in this experimental setup, the test scores of the students should depend directly on the the effects of either of the two conditions mentioned earlier. Hence, it is evident that the test scores of students is the undisputed dependent variable for this experimental setup.

Hope this Helps!!!

Find the volume of the cone.
juin [17]

The answer is 48π units³ or 150.72 units³.

To find the volume of the cone, use the formula : <u>1/3 × πr²h</u>

We are given that r = 6 and h = 4.

Solving :

  • V = 1/3 × π × 6² × 4
  • V = 12 × 4 × π
  • V = 48π units³ (in terms of π)
  • V = 150.72 units³
