Choose and answer and tell me why you chose that !!

A

Step-by-step explanation

I chose this answer because Y and B have the same angle degree and because Y and B are the same angle on both triangles. To me it seems as though ABC and XYZ are the same triangles.

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
