Question

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

Answer 1

Explanation:

Building proportional relationships

$\sf \dfrac{XA}{XY} = \dfrac{XB}{XZ}$

21.

$\sf \rightarrow \dfrac{5}{XY} = \dfrac{10}{18}$

$\sf \rightarrow XY = \dfrac{5(18)}{10}$

$\sf \rightarrow XY = 9$

Then find AY

$\sf AY = XY - XA$

$\sf AY = 9 - 5$

$\sf AY = 4$

$\hrulefill$

22.

$\rightarrow \sf \dfrac{10}{25} = \dfrac{XB}{XB + 3}$

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

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

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

$\rightarrow \sf 15XB = 30$

$\rightarrow \sf XB = 2$

Then find XZ

$\sf XZ = XB + BZ$

$\sf XZ = 2 + 3$

$\sf XZ = 5$

$\hrulefill$

23.

$\sf \rightarrow \dfrac{4}{13} = \dfrac{XB}{26}$

$\sf \rightarrow \dfrac{26(4)}{13} = XB$

$\sf \rightarrow XB = 8$

Answer 2

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.
