Need math help pls:))

  see below

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you of the relationships between triangle sides and trig functions. For the angle of interest, the diagram shows values for the Opposite side (12) and the Adjacent side (16.5). The mnemonic tells you that these are related to the Tangent of the angle:

  Tan = Opposite/Adjacent

  tan(θ) = (12/16.5)

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
