hi, i'm having trouble with another question:(adsbygoogle = window.adsbygoogle || []).push({});

2. A block of weight W is attached to the ceiling by a cord which makes an angle

θ = 30° to the vertical, and to the wall by a horizontal cord. If the tension in the cord

attached to the ceiling is 20 N, the tension in the horizontal cord will be

A) 20 N

B) 17 N

C) 12 N

D) 10 N

I keep getting to wrong answer. I'm really bad with angles and stuff, so I'm not sure how to solve this. Any help would be appreciated.
