Adding 60 Days To Date Column

Aim – To add 60days to [Date_Approved_By_Risk__c] column

Query so far is

select
[Date_Approved_By_Risk__c]
--left([Date_Approved_By_Risk__c],10)+60 as correct_date
from #build
where [Date_Approved_By_Risk__c] is not null

[Date_Approved_By_Risk__c] is in the following format “2010-04-30T23:00:00.000Z”

When i add the following “left([Date_Approved_By_Risk__c],10)+60 as correct_date” into the query i get the following error Msg 245, Level 16, State 1, Line 1
Conversion failed when converting the varchar value '2010-07-13' to data type int.
