Respuesta :

15 cm
N=2m so 3m=1.5n then we can plug in that to get 1.5n+5=n+8 to get the value of n then we do our magic and get n=6 n+9 is 15 and it’s the same length as TU

Answer:

triangle STU and WEK are CONGRUENT

ST=WK SIDE OF A CONGRUENT TRAINGLE ARE EQUAL

2M=N.....1

SU=WE

3M+5=N+8

3M+5=2M+8

3M-2M=8-5

M=3

NOW

N=2M=2×3=6CM

TU=WK=N=6CM.
