Answer:
30 out of 40: 75%
40 out of 50: 80%
40 out of 50 is the better score
It would be 60. He sold his painting for 50 which was 10 less that the original price. So 50+10=60
300; Since EF is the only segment not included in FHE, just subtract the 60 degrees there from 360 to get the sum of the rest of the circle
360-60 = 300
Hopefully this is right, i'm a little rusty on geometry
