Homework Help: Physics please help

Posted by Amy on Monday, May 21, 2012 at 10:38pm.

A 195.0-N sign is suspended from a horizontal strut of negligible weight. The force exerted on the strut by the wall is horizontal. Draw an FBD to show the forces acting on the strut. (Do this on paper. Your instructor may ask you to turn in this work.)The angle is 30 degree

Find the tension T in the diagonal cable supporting the strut.
N

I tried 195sin(30)= 97.5 N, but its wrong. Please someone help me out. Thank you. Sorry for re-posting.
