How to call two services in a single component Angular

I’m trying to call two services in a single Angular component, but I’m getting this following error:
enter image description here

"Service is already defined"
"Subsequent variable delcarations must have the same type"

>Solution :

Use different variables names for each service.

constructor(
    ...
    private service1: AgendamentoServie,
    ...
    private service2: TipoDucomentToService,
    ...
  ) { }
