NeTakaya3 years ago
8 0

Answer:

Step-by-step explanation:

Note that 7pi/6 is equivalent to 6pi/6 + 1pi/6, which is equivalent to pi plus pi/6, or 180 degrees plus 30 degrees.  7pi/6 is in Quadrant III; its "opposite side" is -1 and its "hypotenuse is 2."  Thus, the sine of (7pi/6) is  the ratio

  opp side            -1

------------------- = ------------     This matches Answer B.

-x-x-3=1
-2x-3=1
+3 both sides
-2x=4

x=-2
solve for y
y=-2+3
