(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A ladder is made in the shape of the letter A. Treat the two sides of the ladder as identical uniform rods, each weighing 455 N, with a length of 3.60 m. A frictionless hinge connects the two ends at the top, and a horizontal wire, 1.20 m long, connects them at a distance 1.40 m from the hinge, as measured along the sides. The ladder rests on a frictionless floor. What is the tension in the wire?

2. Relevant equations

Sum of the forces=0

Sum of the torques=0

3. The attempt at a solution

I understand that the ladder can be treated as two separate poles since they are symmetrical. I am just confused as to how to solve it without knowing what the angle is. I tried taking the weight times length (lever arm?) and having that be equal to the tension and the answer I got was 1365N which was incorrect. Any suggestions? Thanks!
