I take it you meant θ angle, anyway.
we know the tan(θ) = -4/7... alrite, we also know that 270° < θ < 360°, which is another to say that θ is in the IV quadrant, where the adjacent side or "x" value is positive whilst the opposite side or "y" value is negative.
Given:
The sets are
and
.
To find:
Whether A and B are disjoint sets or not.
Solution:
Two sets are called disjoint sets if there are no common elements between them.
We have,


Clearly, there is not common elements between the set A and set B.
Therefore, the sets A and B are disjoint sets.
Answer:
D.−√5
Step-by-step explanation:
4 sqrt(20) -3 sqrt(45)
We know that sqrt(ab) = sqrt(a) sqrt(b)
4 sqrt(4) sqrt(5) - 3 sqrt(9) sqrt(5)
4 *2 sqrt(5) - 3 *3 sqrt(5)
8 sqrt(5) - 9 sqrt(5)
- sqrt(5)
