Given the following definitions: U = {1, 2, 3, 4, 5, 6, 7} A = {1, 2, 4, 5} B = {1, 3, 5, 7} How many elements are in A' ∪ B ?
atroni [7]
Answer:
A'∪B has no elements in it
Step-by-step explanation:
C + d = 180°(supplementary angle)
C = 5d
5d + d = 180°
6d = 180°
d = 180°/6
d = 30°
Since C = 5d,
C = 5 x 30°
Therefore, C = 150°

Answer:
10 feet.
Step-by-step explanation:
I am assuming this is a right triangle. We use Pythagoras theorem:
h^2 = 6^2 + 8^2
h^2 = 100
h = 10 feet.
X = -6 + y...so we sub in -6 + y for x in the other equation
x - 3y = 28
-6 + y - 3y = 28
-2y - 6 = 28
-2y = 28 + 6
-2y = 34
y = -34/2
y = - 17
x = -6 + y
x = -6 - 17
x = - 23
solution is (-23,-17)
