Answer:
x = 109 degrees.
Step-by-step explanation:
The angle opposite the 45 degrees = 45 degrees (vertical angles)
Also the angle opposite to the 75 degree angle = 75 degrees for the same reason.
Now if we take the triangle on the left. the bottom right angle
180 - 75 - 45 = 60 degrees ( because the angles in a triangle sum to 189 degrees.
Next we find the left bottom angle of the triangle on the right.
This is 180 - 60 - 79 = 41 degrees (because these 3 angles are on the same straight line).
Finally x = 41 + 68 = 109 degrees ( external angle of a triangle theorem).

Final answer:
To meet the conditions for a hypothesistest assuming independent observations, the sample size should have at least five successes and failures, and the population should be at least 10 or 20 times the size of the sample.
Explanation:
In order to meet the conditions for a hypothesistest that assumes independentobservations in the sample, the sample size should be such that each sample has at least five successes and five failures. Additionally, the population must be at least 10 or 20 times the size of the sample to avoid over-sampling and incorrect results.

Answers
Imagine a line, which a starting point is R and a final point is T. And somewhere in between a point S.
The total distance is RT (from the starting to the final point).
The distance RS is one part of the line, and the distance ST is the other part of the line. If these two distances sum up, you will get the total distance:
RS + ST = RT

therefor set up a ratio and proportiopn
a.
360/2pi=40/x
times 2pix both sides
360x=80pi
divide both sides by 360
x=(2pi)/9 radians
b.
360/2pi=-570/x
times 2pix both sides
360x=-1140pi
divide boh sides by 360
x=-(19pi)/6 radians
a. (9pi)/2 radians
b. (-19pi)/6 radians
