What did you do when you took moments about A? The 679N is correct, but there is a bit of text missing on the previous line. For instance, the equation has no T, but there is also a bit more text missing.

i used trig to find bottom legth f triangle/3 then did 3x sin(30)=20g x 1.5

Why 3*sin(30)? Where is the unknown tension variable in the equation?

How is the left hand side a moment? The right hand side is a moment.

i did Tsin(30)n sorry and LHS is Tsin(30) as the its oppersite the angle and same as rhs force

perpendicular force * distance
You're partially there, but what have you missed out on the left hand side?

i have missed out the 30 but idk where it comes from also the answer has no T so this is more confusing

You have a triangle. The hypotenuse is the tension. How do you resolve that to find the component which is perpendicular to the rod?
