If I used the equation for BD that they gave, I get a negative number. -0.2483?

I found a different equation after some google searching that has it as

BD=2*(tan(A/2)*(R+T)-BA

I got 0.2867 for the BA and 0.4133 for BD using the equation above. 
I didn’t see the BD equation in any of my searching.

Yes, that has already been mentioned.
