here is how the problem looks.

a pullstring walker is in the middle of a string that is connected to two mountain sides. the string formes an angle of 10 degrees under the horizontal. the walker has a mass of 50 KG. find the tension of the string

any idea how to start with this one.if i set up newton 2nd law i get FG-FT+FT= 0
which is useless because FT will cancel out.

when i do the geometry i get an unreasonable answer of

cosθ= adjacent/hyp
cos10= 50/ hyp
hyp=50/ cos10
hyp = 49.24 N.
is that correct?

i did it wrong last time. i belive this is correct. answer is reasonable this time!
