Assuming this is around the origin:
To find the rotation by 90 degrees, it would be (y, -x) (Assuming that the x and y are both variables and number figures)
So therefore, (5, 2) would become (2, -5).
I hope this helped! :)
Answer:
The probability is 
Step-by-step explanation:
Given is that a fair coin is tossed 5 times in a row.
This gives total number of outcomes as = 
As its needed that heads comes exactly 2 times, so favorable outcomes are = 5C2

Solving this we get 10
Therefore, the probability of getting heads exactly 2 times is =
or
