Solving sin2x= (1/2)x (for positive values of x)

I got this as a part of my tutor homework, yet I can't seem to figure it out. It also says to use a graphical method to solve for this equation. I have draw out the lines, but don't know how to find that x intercept point of the 2 lines.

I am also confused to as whether this has anything to do with converting any values to radians as that is part of the current topic, any help would be great, Thanks.
