Prove that ∠b ≅ ∠d, given that ac ⊥ db; ef ⊥ db and ac ≅ ef; ∠a ≅ ∠e

step-by-step explanation:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.  

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
