Solve sinxcosx=0.458: Identities & Isolating Angle

[PhysicsAdvice]

How would i solve sinxcosx=0.458, I cannot determine how to isolate the angle, is there a set of identities i could use? Thanks!

There's a double angle identity that involves sin(x)*cos(x). Check your table of identities.

( You DO keep a table of identities handy, don't you? )
