Chapter P.4, Problem 58E
Solution

Determine a and b so that figure ABCD is a parallelogram.

  PRECALCULUS:...COMMON CORE ED.-W/ACCESS, Chapter P.4, Problem 58E , additional homework tip  1

  a=3

  b=4

Given information:

ABCD is a parallelogram.

Concept used:

  • First, find the value for x on the x-axis.
  • Next, find the y-value on the y-axis.
  • The point should be plotted at the intersection of x and y.
  • Finally, plot the point on your graph at the appropriate spot.
  • Then join all the points to make a closed figure for calculating perimeter and area.

Calculation:

ABCD is a parallelogram.

  PRECALCULUS:...COMMON CORE ED.-W/ACCESS, Chapter P.4, Problem 58E , additional homework tip  2

The opposite side of parallelogram are equal.

From figure b is equal to 4

  b=4

AB=CD and BC=AD

Using distance formula −

  AB=(x1x2)+(y1y2)=(0a)2+(04)2=(a)2+(4)2=a2+16

  CD=(x1x2)+(y1y2)=(85)2+(40)2=(3)2+(4)2=9+16=25=5

As AB=CD

  5=a2+16onsquaringbothside25=a2+16a2=2516a2=9a=3
