Please provide explanations
From the document, we all know the answer is 1
Here's how - OP, we can calculate to be 2. So OPQ is a right triangle with sides, 2,2,x (x being hypotenuse, PQ).
PQ = sqrt(4+4) = 2 * sqrt(2).
So s = PQ - horizontal distance of Q from y-axis
s = 2 * sqrt(2) - sqrt(3) (since x-value of P is sqrt(3).
sqrt(2) ~ 1.4; sqrt(3) ~ 1.7
Hence, s = 2.8 - 1.7 ~= 1.
Sorry if the symbols are confusing!
