# Vector Triangle Watch

1. I have attached a question about vector triangles and how i would work it out. Cant think of a way forward apart from sine rule
Any mistakes in drawing the triangle? Just wanting you guys to check

2. {T1}sin(40) + {T2}sin(60) = 35g

{T1}cos(40) = {T2}cos(60)
3. (Original post by DeanK2)
{T1}sin(40) + {T2}sin(60) = 35g

{T1}cos(40) = {T2}cos(60)
Hey, i thought of doing it that way
but how come T1cos40 = T2cos60 ??
I know that the sum should be equal to 35g, tried that way but couldnt progress further

EDIT: got it, horizontally should also be equal because in equilibrium, thanks for your help

EDIT AGAIN : Then also, i still dont get it would you get 2 relations then solve?

5. You can use the sine rule to find T1 and T2

Then repeat for T2.
