Answer:

Step-by-step explanation:
The area for a parallelogram is given by the formula:

Where b is the base length and h is the vertical height.
The base length is 16.9 while the vertical height is 8.7. Thus:

Multiply using a calculator:

Answer:
1.Isolate y
3y=10-8x
y=10/3-8/3x
2.Put in correct format (y=mx+b)
y=-8/3x+10/3
y= -8/3x+10/3
slope is -8/3 and y-intercept occurs in 10/3 or 3.333
Answer:
the answer is DBC=90°
because the midpoint of the perimeter of quadrilateral is B
