Answer:
The angles are 79.45, 59.02 and 41.53 degrees to the nearest hundredth.
Step-by-step explanation:
We have a triangle with sides of length 8.6, 5.8 and 7.5 feet.
Using the Cosine Rule to find the measure of the angle opposite the side of length 8.6 feet:
cos X = (8.6^2 - 5.8^2 - 7.5^2) / ( -2*5.8*7.5)
= 0.18310
X = 79.45 degrees.
We can now find another angle using the sine rule:
8.6 / sin 79.45 = 7.5/ sin Y
sin Y = (7.5 * sin 79.45) / 8.6
Y = 59.02 degrees
So the third angle = 180 - 79.45 - 59.02
= 41.53 degrees.

Step-by-step explanation:
Independent samples are samples that are selected randomly so that its observations do not depend on the values other observations. Thus, this sampling is independent. The sampling is independent because an individual selected for one sample does not dictate/affect which individual is to be in the second sample.
The variable is qualitative because it is an attribute classification. A qualitative variable are variables that are not numerical. It describes data that fits into categories (personality type).
