Math Problem Statement

Line segment WZ is shown below and where WX = 2x, XY = 3x + 1, YZ = 8, and WZ = 29. Match missing measures.

Solution

To solve for the missing measures on line segment WZWZ, we use the information provided:

  • WX=2xWX = 2x
  • XY=3x+1XY = 3x + 1
  • YZ=8YZ = 8
  • WZ=29WZ = 29

The total length of line segment WZWZ is the sum of WXWX, XYXY, and YZYZ: WZ=WX+XY+YZWZ = WX + XY + YZ Substituting the given expressions into this equation: 29=(2x)+(3x+1)+829 = (2x) + (3x + 1) + 8 Now simplify and solve for xx: 29=2x+3x+1+829 = 2x + 3x + 1 + 8 29=5x+929 = 5x + 9 Subtract 9 from both sides: 20=5x20 = 5x Now divide by 5: x=4x = 4

Step 2: Finding the missing measures

Now that we know x=4x = 4, we can substitute it back into the expressions for WXWX and XYXY:

  • WX=2x=2(4)=8WX = 2x = 2(4) = 8
  • XY=3x+1=3(4)+1=12+1=13XY = 3x + 1 = 3(4) + 1 = 12 + 1 = 13

So the missing measures are:

  • WX=8WX = 8
  • XY=13XY = 13
  • YZ=8YZ = 8 (already given)

Summary of measures:

  • WX=8WX = 8
  • XY=13XY = 13
  • YZ=8YZ = 8
  • WZ=29WZ = 29 (total length)

Would you like any further clarification or details?

Here are 5 follow-up questions to expand your understanding:

  1. How can we verify the total length WZWZ from the segment measures?
  2. What happens if we change the value of YZYZ while keeping WZWZ constant?
  3. How would the expressions change if WZWZ were given as a variable instead of a number?
  4. Can you find an alternate method to solve for xx in this type of problem?
  5. How would you solve for missing lengths if you were given angle measures instead?

Tip: When solving geometry problems, always remember that the sum of smaller segment lengths equals the total length of the larger segment.
