Answer:
B 16
Step-by-step explanation:
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.
