Answer:

x= 18

RZ= 114

RT= 228

Step-by-step explanation:

so if Z is the midpoint of RT then that means Z divided RT in half
meaning RZ=ZT
so you now know what RZ is because ZT=114
and RT is just RZ+ZT so RT= 114+114 =228

the hard part is solving for x

if RT=ZT then 7x–12=114
start by adding 12 on both sides
you get 7x=126
then divide 7 on both sides
you get x=18
