the line and the height of the balloon are two sides of a right triangle
__ the distance between the anchor point of the line and a spot directly under the balloon forms the 3rd side

the line is the hypotenuse and the height is opposite the 85° angle

let x=height __ so sin(85°)=x/20 __ 20(sin(85°))=x
