Hello from MrBillDoesMath!
Answer:
283 degrees
Discussion:
A circle has 360 diverges so summing up all the angles gives:
360 = (7y - 7) + (20y-11) + (4y + 6) => combine like terms
360 = (7y + 20y + 4y) + (-7 - 11 + 6) =>
360 = 31y - 12 => add 12 to both sides
372 = 31y =>
y = 372/31 = 12
measure arc ABC =
360 - measure arc (7y-7) =
360 - (7*12-7) =
360 - (77) = 283
Thank you,

Answer:
30%
Step-by-step explanation:
Total population=15,000
kantipur=9000
gorkhapatra= 7500
Both magazine=40%
n(k intersection g)=40% of 15,000
=0.4*15,000
=6,000
n(k) =9000
n(g)=7500
n(A union B)= n(k) + n(g) -n(k intersection g)
=9000+7500-6000
=10,500
Population who do no read= Total population - n(A union B)
=15000-10500
=4500
Percentage population who do not read both magazine
=4,500/15,000 * 100
=0.3 * 100
=30%
