A rope dancer was walking on a loose rope tied to the tops of two equal post of height 9m. when he was 2.7m above the ground ,it was found that the stretched parts of the other rope made angles of 30 and 60.Find the length of the rope,with figure
Answered by oobleck

(90-2.7) / cosθ
where θ is 30° or 60°

no idea where the "other rope" is ...
