Answer: A: V is an acute angle, so it is less than 90 degrees. I would say it's around 45 degrees.
B: K is also an acute angle, but it is fairly close to being 90 degrees, so I'd say around 80 degrees.
C: Q is an obtuse angle, so it is over 90 degrees but less than 180 degrees. I would say it's around 110 degrees.
D: Y is an obtuse angle. It is very close to 180 degrees. I would say it's around 160 degrees.
Step-by-step explanation:
A = {x ≥ 3}, B = {x ≤ 1}
So A∪B = {x ≥ 3 or x ≤ 1}
So for x ⊆(1,3), A∪B = ∅
Apparently, (1,3) covers the first option, a will be the answer
