#T~=918,075N" left tension"# #R~=844,443N" right tension"#
Explanation:
#"you may use sine theorem:"# #535/sin145=T/sin100# #535/sin 35=T/sin 80# #535/(0,574)=T/(0,985)# #T=(535*0,985)/(0,574)# #T~=918,075N# #"for the right tension:"# #535/sin145=R/sin 115# #R=(535*sin 115)/sin 145# #R=(535*0,906)/0,574# #R~=844,443N#
