Answer:
P(A) ∪ P(B) ⊆ P(A ∪ B) can be proved when 
∈ P ( A U B )
Step-by-step explanation:
To Prove that P(A) ∪ P(B) ⊆ P(A ∪ B) is attached below and also a counter example to prove that we do not always get an equality is attached below as well
By using the fact that the two triangles are equivalent, we will find that the value of n must be 18.4

How to find the length of n?</h3>
Here we can see that the horizontal line divides the triangle in such a way that the left and right sides are divided in two halfs. (we can see this because both parts have the same symbol on them)
Also both of these triangles are equivalent, so:
if x is the measure of each part in the right side we can write the equivalent relation
11.3/x = (n + 4.2)/(2x)
Now wen solve this for n:
(11.3/x)*2x = (n + 4.2)
22.6 = n + 4.2
22.6 - 4.2 = n
18.4 = n
