Answer:
The larger angle is 144 degrees and the smaller angle is 36 degrees
Step-by-step explanation:
Because this is a supplementary angle you have to find out what x is to solve this equation
Because 2.4x and 9.6x are like terms we add them
So now to find x we divide 180 by 12 to get 15
We replace the x with 15
We add 36 and 144 which equals 180

The sample size should be 250.
Our margin of error is 4%, or 0.04. We use the formula
To find the z-score:
Convert 98% to a decimal: 0.98
Subtract from 1: 1-0.98 = 0.02
Divide both sides by 2: 0.02/2 = 0.01
Subtract from 1: 1-0.01 = 0.99
Using a z-table (http://www.z-table.com) we see that this value has a z-score of approximately 2.33. Using this, our margin of error and our proportion, we have:
Divide both sides by 2.33:
Square both sides:
Multiply both sides by n:
Divide both sides to isolate n:
