assume origin to be (0,0)
point of passing is (3R/4,R/4)
now you find the distance between origin and the given point
also point right below (3R/4,R/4) intersecting the x-axis is (x,0)
find (x,0)
then find the distance between (3R/4,R/4) and (X,0)
then
Sin(alpha*pi/180) = length of opp side/hypotenuse
point of passing is (3R/4,R/4)
