Answer:
x=8 or x=-2
Step-by-step explanation:
x²-16=6x
x²-6x-16=0
x²-8x+2x-16=0
x(x-8)+2(x-8)=0
(x-8)(x+2)=0
either,. or.
x-8=0 x+2=0
x=8 x=-2
Answer:
Step-by-step explanation:
3π/2 is equivalent to 270°. The "opposite side" for this angle is -2; the adjacent side is 0, and the hypotenuse is 2.
Thus, sin 3π/2 = opp/hyp = -2/2 = -1, and
cos 3π/2 = adj/hyp = 0/2 = 0.
