Answer: 
Step-by-step explanation:
this forms a 30 degree reference angle
and this is in the 4th quadrant
When the angle is 30 degrees, the coordinates are:

3x - 2y = 8 +
===》 46x = 16
43x + 2y = 8
x = 16/46
x = 8/23
______________________________
3x - 2y = 8
3(8/23) - 2y = 8
24/23 - 2y = 8
2y = 24/23 - 8
y = 12/23 - 4
y = 12/23 - 92/23
y = - 80/23
Answer:
75cm²
Step-by-step explanation:
area of parallelogram= base*height
area=15*5=75cm²
4-70=7-6x
-64-7=6x
-71=-6x
71/6=x
