<u>Given</u>:
Let X and Y be two sets.
The two sets are given by
and 
We need to determine the value of the set 
<u>Value of the set </u>
<u>:</u>
The value of the set
is the set that contains all the elements that are at least in one of the two sets.
Hence, the union of the set
is given by


Arranging in ascending order, we get;

Thus, the union of the sets X and Y is 
Answer:
1. -1/2b
2. 3a/b^2
3. 3b^2/1a^2
4. -1a^2b/2
Step-by-step explanation:
Simplified answers and then the variables cancel out each out as much as they can (That's the best way to explain it)
Answer:
Could you please show the circle ?
Step-by-step explanation:
Two angles are called complementary if their measures add to 90 degrees, and called supplementary if their measures add to 180 degrees.
In radians this are

To find the complement of 3π/4, subtract it by π/2

To find the supplement of 3π/4, subtract it by π.
