Why am I being told im trying to call a table value?

I am quite sure this code should work, but it wont actually run.

local Part = script.Parent

local newPos = CFrame(15,20,15)

local newAngle = CFrame.Angles(math.rad(15),math.rad(20),math.rad(15))

Part.CFrame = newPos 

Part.CFrame = newAngle

It gives me this error on the output:

Workspace.Part.Script:3: attempt to call a table value

I do not understand how I am trying to call a table value, this is not in any other scripts on my place.

Plus pointing out any inefficient code would be appreciated!

it's

	local newPos = CFrame.new(15,20,15)
