a 25 kg chandelier is being temporarily supported by two chains of length 7m and 9m attached to two points in the ceiling 11m apart. find the tension in each rope.

i first get all the angles of the triangle formed, i do
245/sin94.5=T1/sin35.3=T2/sin50.6
T1=142N T2=190N

What, exactly, are you "doing" in your last two lines? What was your reasoning? For what do the variables stand? How did you arrive at your results? Are you requesting help with something, a check of your final answers, or something else?

Please be complete. Thank you! ;)
 
I basically use sine law to find the other tension. but i am not sure if i did it in the correct way

Since we "basically" have no way of knowing what were your specific steps and reasoning, we "basically" cannot respond. Sorry. ;)

Your answers are correct to 3 significant digits.

However, as Stapel pointed out, you need to explain your work better to get full credit for your answers (under most situations).
