Answer:
64°
Explanation:
So supplement angles are equal to 180, so first our two angles added together will be 180:
x + x = 180
Now one of these angles is 6 greater than half:
x + (x/2 + 6) = 180
Then we will solve for x:
x + (x/2 + 6) = 180
x + x/2 + 6 = 180
x + x/2 = 174
x = 174
x = 116
Plug it back in:
x + (x/2 + 6) = 180
/\
x/2 + 6
(116)/2 + 6
64
To check:
116 + 64 = 180 ✓
