Answer:
This question is a lot easier than it seems. What you have to do here is subtract 6 1/9 from 7.
This will give you 0.8 of the fabric left, or 8/9.
Let the measures of three angles be 5x, 7x, 8x
Sum of angles of a triangle = 180°
5x + 7x+ 8x = 180°
20x = 180
x = 180/20 = 9
First angle = 5x = 5*9 = 45°
Second angle = 7x = 7*9 = 63°
Third angle = 8x = 8*9 = 72°
