Answer:
- x = 12
- 3x+1 = 37°
- 10x-11 = 109°
- 3x-2 = 34°
Step-by-step explanation:
Perhaps you want to know the value of x or the measures of the angles?
__
Simplifying the given equation, you get ...
(16x -12)° = 180°
16x = 192 . . . . . . . divide by °, add 12
x = 12
(3x+1)° = (3·12+1)° = 37°
(10x-11)° = (10·12-11)° = 109°
(3x-2)° = (3·12-2)° = 34°
x is 12, and the angle measures are 37°, 109°, 34°.
