Discrete Mathemathics

Validate the following argument using propositional logic, with a diagram and the corresponding table consisting of statements and reasons.

If DeWayne is not tall then Jayden is not DeWayne's brother. If DeWayne is tall then Trevor is DeWayne's brother. Therefore, if Jayden is DeWayne's brother, then Trevor is DeWayne's brother.

I have the symbolic rule but I do not know how to make a diagram and corresponding table to prove it,

7=not

D=DeWayne is tall

J=Jayden is DeWayne's brother

T=Trevor is Dewayne's brother

(7D --> 7J) and (D --> T) => (J --> T)
