Answer:

66.423 degrees

Step-by-step explanation:

The diagram is a right-angled triangle. It has two known sides and one known interior angle which is 90 degrees. The side opposite to the 90 degrees is called the Hypotenuse. it is also the longest side.

To find an angle, you need to know two sides. Per the angle at Y or angle XYZ, XY is adjacent. Using the adjacent XY and Hypotenuse YZ, we can write an expression using the trigonometric ratio called Cosine.

That's, Cos XYZ= 6/15

Angle XYZ=Cosine Inverse of 6/15

Angle XYZ=66.42. (2 dp)

Answer:

66.4°

Step-by-step explanation:

cos XYZ = XY/ZY = 6/15 = 2/5 = 0.4

Using a calculator for cos^(-1) of 0.4 you get 66.42182152°

In a causal-comparative study, what is the difference between independent variables and dependent variables? independent variabl
AlladinOne [14]

Answer: independent variables cause the effect measured in the dependent variables

Step-by-step explanation: In a causal - comparative study, the dependent variables refers to the variable whose changes is being measured or observed. The changes or alteration of the dependent variable is induced by the different values of the independent variable. In causal - comparative study, the different independent variables is assumed to have a direct impact on the output or values of the dependent variable which is measured by the experimenter. Therefore, the independent variable does not change, but causes the observed changes noticed in the dependent variable.
