Answer:
A U B = {1,2,3,4,5,6,8}
Step-by-step explanation:
Let's define the sets.
Let ¢ = universal set ( Contains all the elements in the set)
¢ = {1, 2, 3, 4, 5, 6, 7, 8, 9 , 10}
A= {2, 4, 6, 8}
B= {1,2,3,4,5,6}
Therefore: A U B (A union B):
A U B = {1, 2, 3, 4, 5, 6, 8}
Answer:2nd option
Step-by-step explanation:
I took the test
Answer:
x = 30
Step-by-step explanation:
We know that the angle is a right angle, which is equal to 90. So in order to see what the equation is equal to, we have to subtract 81 from 90.
90 - 81 = 9
With the answer we get, we can now begin to solve for x.
2x - 51 = 9, add 51 to both sides
2x = 60, divide 60 by 2 to get x
x = 30
Now, to check your work, plug 30 into the equation.
2(30) - 51
60 - 51 = 9
hope this helps!! :]
