Answer using system of equations

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
