Hope this helps!

here you hope this .

step-by-step explanation:

hypotenuse = √(15² + 8²)

=  √(225 +64)

=  √(289) = 17

sin(x) = cos(y) = 8/17

they are identical so long as you are doing the sine of one angle and the cosine of the only other angle that isn't the right angle.

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
