Answer:
9:12 and 12:16
Step-by-step explanation:
3/4 = 0.75
9/12 = 0.75
12/16 = 0.75
4(5x - 2) - 2(9 - 3x)
= 26x - 26
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.
