The two angled ropes used to support the crate in the figure below an withstand a maximum tension of 1300 N before they break. The left angle is 30dregres, and the right angle is 45degrees. What is the largest mass the ropes can support? m=?

look at the horizonal (I assume the angles are measured to the horizontal).
and the vertical..
so solve for Tleft in the first equation:
solve for Tr. Put that in the equation for tleft. Then set it equal , 1300N
thensolve for mass.

is the answer 123.79 kg? or Newtons? thank you for the help

it should be in kg.

..... isnt it Trcos45-Tleftcos30= 0
Tr = Tleftcos30/cos45?
