Convert Feet to Decimal Degrees

I want to have a piece of code to convert a custom coordinate system (LDP NAD 1983 [NSRS2007] US Feet) into Decimal Degrees. The projection of the dataset is detailed below:

Projection: Lambert_Conformal_Conic
False_Easting: 200000.0
False_Northing: 150000.0
Central_Meridian: -77.03333333333333
Standard_Parallel_1: 38.83333333333334
Standard_Parallel_2: 38.83333333333334
Scale_Factor: 1.0
Latitude_Of_Origin: 38.83333333333334
Linear Unit: Foot_US (0.3048006096012192)

Geographic Coordinate System: GCS_NAD_1983_NSRS2007
Angular Unit: Degree (0.0174532925199433)
Prime Meridian: Greenwich (0.0)
Datum: D_NAD_1983_NSRS2007
Spheroid: GRS_1980
Semimajor Axis: 6378137.0
Semiminor Axis: 6356752.314140356

I want to mathematically to do calculations. I found a piece of code at coordinate system - Convert Feet to Decimal Degrees - Geographic Information Systems Stack Exchange but this piece of code does not explain clearly how to use the values of False_Easting & False_Northing. Do you have an idea how to do it? Thanks.
