Question

Please can you tell me if my diagram is correct and how i did it is correct

Is this correct that I can use 31 for my angle because it an opposite angle to the angle given in the picture

(a) Find the tension in each cable supporting the 540-N cat burglar. (Assume the angle θ of the inclined cable is 31.00.) inclined cable horizontal cable vertical cable T, sin 31° -540 T,(0.5150) T2(0.5150) T, cos 31°-T, = 0 T, cos 31° T2 cos 31° =T 1048 cos 31° T 898 = T 0 = Tension force +540 540 = 540 2 T2 sin 31° =540 Tension force 31.0 (0.5150) 540 T,cos 31° χ 0.5150 0.5150 540 N T, 1048 2 T, = 540 vertical cable T1048 inclined cable T 898 horizontal cable x = T, cos 31° y = 540 y = T, sin 31。 Is this correct that I can use 31 for my angle because it an opposite angle to the angle given in the picture

    please explain why my lecturer solved it the way he did. Why is thetta in his figure SW (to the right of the negative y axis)? I put thetta on the WN (above the negative x axis) because I know thats equivalent to the given one. Second, why does he include the ma(dice) as a force? isnt this supposed to be what the sum of our forces are equal too? why did he include it in the sum of forces....

    Can someone tell me where I'm going wrong? I have these two problems: The professor uploaded a video explaining how to solve them (generally, he didn't use numbers. He said the steps are the same for both problems except for the last step since the first problem is asking for magnitude and the second is asking for an angle. I followed his steps but I keep getting the wrong answer.) Also for the 2nd question I'm not sure if I'm...
