Prove that: sin4A/1+cos4A*cos2A/1+cos2A=tanA​

the one that has a slope of 1/2 and is positive.

step-by-step explanation: 2 buckets 1 trip ; 4 buckets 2 trips and so on.

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.

true

step-by-step explanation:

intersecting chords are just lines that intersect. so a line is equal to 180 degrees, so when it is intersected by another chord, then it create supplementary angles, and because the lines cross, vertical angels are also formed.
