72 - 13 = 59
We have now
20 + 15(59) - 67 + 6
20 + 885 - 67 + 6
905 - 67 + 6
905 - 61
844

Answer:
Step-by-step explanation:
Let the two angles be x and y
Then: y = 5x - 6
And x + y = 180° (the of supplementary angle is 180°)
Putting y = 5x - 6
x + 5x - 6 = 180
6x = 180 + 6
6x = 186
x = 186/6
x = 31°
And y = 5x - 6
y = 5(31) - 6
y = 155 - 6
y = 149°
The angles are 31° and 149°
