Why is my static IP address not set to what I made it in the /etc/sysconfig/network-scripts/ifcfg-enp0s3 file?

I have made the following changes to /network-scripts/ifcfg-enp0s3 file in order to try and get a static IP address (added ip i want ending in .49, added gateway, Prefix and Subnet mask ( But i get this error message when I attempt to restart network (image of error included) When I check Jornalctl -xe I get this (image included) *Possible solution i found: “If you are using NetworkManager there will be more items that you would need to configure like: GATEWAY, DOMAIN, DNS1, DNS2, etc. If you are not using NetworkManager, you will need to configure the gateway address in the /etc/sysconfig/network file, and the DNS resolvers (if required) in the /etc/resolv.conf file I added DNS="8/8/8/8".” **But I do not know how to configure DNS, Domain etc.***
