Heyo Kiddo. How are you doing today?
Let's figure this out.
So in number form, the equation will be looking a little like this:

To solve.

So I hope this answers your question and that you have a great day. :)
If the triangles are similar, then the corresponding ratio of their sides have equal ratios. Through ratio and proportion, we would determine the answer.
5/6 = x/9, where x is the length for side PN
Transposing the equation so that x is on the left side:
x = (5/6)*9
x = 7.5
No of substes is given by 2^n where n is the no of elements.
Here, n = 3
Therefore, number of subsets = 2^3 = 8
