T1cos 30o + T2cos 80o = 700
Find T1 and T2
It's a forces problem
Army, Navy or RAF?
1 equation. 2 unknowns.
Can't be solved without additional information.
t1= CBA
t2=DILLIGAF

You need another constraint, surely? There must be something else in the problem giving you an expression in T1 and/or T2.
Is this something being suspended by two ropes at an angle?
In which case you have solved for vertical equilibrium by stating the vertical components from the tension in the rope is equal to the weight of whatever is being supported.
The second equation should be for horizontal equilibrium - if the object is not moving then there is no overall horizontal force so
T1sin60=T2sin80

W = 700N
What is the tension in each rope. Not to be solved graphically.
Your other constraint is T1.Sin(15) - T2.Cos(10) = 0 (she's not accelerating left or right).
Just substitute T2=T1.Sin(15)/Cos(10) into the first equation - and solve for T1 (though I think the angles are different in the illustration and your original example?)
Where's Bruneep? He'll know this one, although I'm sure thats not standard operating procedure 😀
Check your angles are labelled in the same place as the diagram. Euains equation is correct, but if you angles are labelled in the same position then your initial equation is wrong as one of the angles is measured to the horizontal and one is measured to the vertical.
Unfortunately before I solved the equation the flames burnt through the rope and the poor lady plunged to her death.
So the problem changes and the solution now becomes "time for a cup of tea".

Tell the cage operator to move closer and stop dicking about
😆
Where's Bruneep? He'll know this one,
He's down below and has deduced 'T1' is 'collar' and 'T2' is 'cuffs' and that they both match.
