Find the tension in the two wires supporting the 36 kg traffic light shown in Fig. 12-57. (Assume that 1 = 52° and 2 = 38°.)

2. Relevant equations

-T1cos(52)+T2cos(38)=m*g

T1sin(52)+T2sin(38)=0

3. The attempt at a solution

so I found T1=-T2sin(38)/sin(52)

and plugged into the first equation and got

[sin(38)*cos(52)/sin(52)+cos(38)]*T2=353.16

and got T2 = 278N

and T1=217N

but when I put it into the webassign it is wrong...

so what am I doing wrong?
