Given A = {a, e, i, o, u} and B = {a, l, g, e, b, r}, find A ∪ B.

Ahh..this is sets topics - A U B = all the elements found in A and B. But do note, do not repeat the elements if it is the same. And if the question were to ask : n(AUB) = total number of elements found in A and B.
8 2/5 ÷(-2 1/5) = -3.81818181818
Step-by-step explanation:
in this situation
A+B =D
Height covered by the plane=h= 500 feet
Distance covered by the plane along the ground=d= 2 mile
Now, convert the mile into feet,
1 mile = 5280 feet
2 mile = 10560 feet
Now, use the formula
h= d tanθ
tanθ= h/d
tanθ= 500/10560
tanθ= 25/528
Take the tan⁻¹ on both side,
θ= tan⁻¹(25/528)
θ =2.71°
According to my calculations the theoretical answer about to be given is number c
