I beleive the answer is 1. The triangle POQ is a right angled triangle.Finding the distance between two points P and O we get the PO=2 and since PO=OQ=radius hence it is also isoceles triangle.We now have two equations
1 distance between points Q and O = 2
2 distance between points P and Q = sqrt(2 )

Solving for 2 unknowns s and t we get s=1

Its Sqrt(3)

From the Diagram we can find out the radius of the circle = 2

Now , from the values of P we can deduce the angle of PO with the X axis to be 30 degrees. (1,2,Sqrt(3) sides of a 30,60,90 triangle)

So the angle subtented by OQ with the X axis is 180 - 90 -30 = 60

Now we know its also makes a 30-60-90 triangle with the X axis with a hypotenuse of 2 and we can arrive at the value of S.

Not sure how this is happening. t = s√3 from the equations. Now substituting this relationship in the equation s^^2 + t^^ 2 = 4 (and noting that s, t >0) e get s =1 and t = √3.

Yes it should be s=1

I had everything right except the answer.
Messing bigtime :beat:
