The value of n and YZ are 13 and 26 respectively
If Y is between X and Z, then:
XY + YZ = XZ
Given the following
XY = 5n
YZ = 2n
XZ = 91
Substitute the given expressions into the formula as shown:
5n + 2n = 91
7n = 91
Divide both sides by 7
7n/7 = 91/7
n = 13
Get the measure of segment YZ
YZ = 2n
YZ = 2(13)
YZ = 26
Hence the value of n and YZ are 13 and 26 respectively
