This picture should help, i graphed it for you! : )
Two angles are equals.
Suppose they are 6y.
Then 6y + 6y + 8y - 16 = 180
20y = 180 +16
20y = 196
y = 9.8
Then one base angle is 6*9.8 = 58.8°
And the other base angle is 8(9.8) - 16 = 62.4.
Now suppose that the two equal angles are 8 y -16
Then 8y -1 6 + 8y - 16 + 6y = 180
Then 16y - 32 = 180
16y = 180 + 32
16y = 212
y = 13.25
One angle is 6(13.25) = 79.5
And the other is 8(13.25) - 16 = 90
This last solution is imposible.
So the answer is 58.8 and 62.4
Answer:
42.29, 42.25, 42.32

Hope this helps but I think the answer is 12.
