Alright, so first we need to establish two things.
First, the compliment of a set is like the extreme opposite; everything that is not in set B will be in the complement.
Second, we need to find out what B is.
Okay, so B is everything that is greater than 2, that's given. That includes 3, 4, and 5. B = {3, 4, 5}. There are three items in this set.
The numbers that aren't included are 1 and 2. The complement of B, let's call this C I guess, is C = {1, 2}. There are 2 items in this set.
The answer, I believe, is <em>two</em>. Hope this helps!

Answer:
The speed of the jet in still air is 260 miles per hour.
Step-by-step explanation:
Given that a small jet can fly 858 miles in 3 hours with a tailwind but only 702 miles in 3 hours into a headwind, to find the speed of the jet in still air the following calculation must be performed:
858/3 = 286
702/3 = 234
(286 - 234) / 2 = X
52/2 = X
26 = X
286 - 26 = 234 + 26
260 = 260
Therefore, the speed of the jet in still air is 260 miles per hour.
