I don't understand what this is asking. Are these lengths, angles or is this some kind of puzzle which just has numbers put in?

Hello alternative,

three parallels and two transversals

to understand this draw a line parallel to the right side transversal thru the left side transversal atthe top parallel and left transversal intersection.You then have a triangle in which the four lenghts are proportional as a property of similar triangles.
