Answer:
x = 9
Explanation:
To answer this equation We have to find the value of x so that and A, B, and C add up to 180. Since angle A and C are both 6x that means the number of those angles are the same. Therefore the equation for this problem is:
180 = 6x + 6x + 8x
Now substituting 9 in for the x values;
180 = 6(9) + 6(9) + 8(9)
180 = 54 + 54 + 72
180 = 180
