Let S be the universal set, where: S = {1, 2, 3, ..., 18, 19, 20}
Let sets A and B be subsets of S, where:
Set A = {1, 10, 11, 12, 14, 15)
Set B = {1, 3, 9, 11, 12, 14, 15, 16, 19, 20}
Set C = {3, 4, 5, 8, 11, 12, 13, 16}
Find the number of elements in the set (AU BUC)
n(AU BUC) =
Find the number of elements in the set (An BNC)
n(An Bn C) = 1

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length

the radius is 2 times the diameter.

after 1 year: 221 deer

step-by-step explanation:

30% of 170 is 51. 170+51=221
