Which expression is equivalent to 4sin?(x) – 8sin?()? 4(cos(x) - cos?(x))
4(-cos(x) - cos(x))
4(2 - cos(x) – cos(x))
4(2 + cos(x) - cos?(x))

astronomers is your final answer! : )

step-by-step explanation:

∆abc has the points a(1, 7), b(-2, 2), and c(4, 2) as its vertices. formed with the point d(1, 2) as its third vertex, then ∆abd is triangle.

seems like d
