Question

PLEASE HELP ASAP!!!! I HAVE THE ANSWERS BUT I NEED THE WORK FOR THESE THREE PLEASE ITS URGENT

Answer 1

Answer: The solution is x=7.

Step-by-step explanation: Using the segment addition posyulate we can find the measure of the segment. given it is 4, 5, 8.

Answer 2

Step-by-step explanation:

Building proportional relationships

`\sf (XA)/(XY) = (XB)/(XZ)`

21.

`\sf \rightarrow (5)/(XY) = (10)/(18)`

`\sf \rightarrow XY = (5(18))/(10)`

`\sf \rightarrow XY = 9`

Then find AY

`\sf AY = XY - XA`

`\sf AY = 9 - 5`

`\sf AY = 4`

`\hrulefill`

22.

`\rightarrow \sf (10)/(25) = (XB)/(XB + 3)`

`\rightarrow \sf 10(XB + 3) = 25XB`

`\rightarrow \sf 10XB + 30 = 25XB`

`\rightarrow \sf 25XB-10XB = 30`

`\rightarrow \sf 15XB = 30`

`\rightarrow \sf XB = 2`

Then find XZ

`\sf XZ = XB + BZ`

`\sf XZ = 2 + 3`

`\sf XZ = 5`

`\hrulefill`

23.

`\sf \rightarrow (4)/(13) = (XB)/(26)`

`\sf \rightarrow (26(4))/(13) = XB`

`\sf \rightarrow XB = 8`
