Question

In the figure below, XZ=35 and YZ=17. Find XY.

Answer 1

$\sf \: XZ=XY+YZ \\ \tt \: [by \: segment \: addition \: postulate]$

$\bf \: 35=XY+17$

$\bf \: 35 - XY = 17$

$\bf \: - XY = 17 - 35$

$\bf \: - XY = - 18$

$\boxed{ \rm \: XY = 18}$

Answer 2

Answer:

XY = 18

Step-by-step explanation:

XY → XZ - YZ      [ here given XZ is 35 and YZ is 17 ]

XY → 35 - 17        [ subtracting ]

XY → 18               [ final answer ]
