The halves of the string make 35 degrees with the vertical. What is the tension in the string? What is the tension in the string?

I think the top answer is wrong, the second way gets the correct answer but goes about it in a strange way (the arrow is being pulled back horizontally..?)

Here is my contribution:

The angles below are not correct but hey, a diagram always helps

Tension

Each part of the string has a Tension contributing to keeping the forces in equilibrium. Vertically, T cos35 = T cos 35 , which doesn't help.

Solving horizontally: T cos 55 + T cos 55 = 90

2 T cos 55 = 90

T cos 55 = 90 /2 = 45

T = 45 / cos 55

T = 78N
