Coh: sin(theta) = Opp/Hyp
sin(theta°) = AC/AB
sin(70°) = AC/4
AC = 4*sin(70°)
AC ≈ 3.758770483
AC = 3.76
Answer:
18%
Step-by-step explanation:
Non fiction books - 72
Fiction Books - 328

Answer:
{2, 3, 5, 6, 8, 9}
Step-by-step explanation:
The universal set is
U = {2, 3, 4, 5, 6, 7, 8, 9}
M = {3, 4, 7, 9}
N = {4, 6, 7}
M n N = {4, 7}
The bar above M n N means the complement of M n N which is all elements of the universal set that are not in M n N.
Answer: {2, 3, 5, 6, 8, 9}
