If you substitute in the values for x and input the value for b in both equations and solve you should get the same degree measure.
Input the vale for b which is 16
substitute 16 for x (8(16) + 14)°
Multiply 16 by 8 and you would get 128
Then add 14 to 128 and you would get 142° for the measure of 1 angle
Then do the same for the other equation to see if you get the same value:
substitute 16 for x (12(16) - 50)°
Multiply 16 by 12 and you would get 192
Then subtract 50 from 192 and you also should get 142°for the other angle
So the answer is B because when you input the value into both of the equations and solve, the measures of the angles are the same. The other values when you input them in the equations for x you get different angle measures.
Because of probability, a green or red bead would be drawn 14/20 times because there are 20 total beads and adding together the numbers for green and red. From this, if you multiply by 3/3 you can see that 42/60 times it will be a green bead. A reasonable prediction for green beads would then be 42 times. Hope it helps :D
