Hello, Could anyone help me solve this ?
I'd really appreciate your help.Thanks
Hello alternative,
three parallels and two transversals
answer 16/20=18/x
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.
