[tex]\\ \rm\Rrightarrow TR^2=16(9)][/tex]
[tex]\\ \rm\Rrightarrow TR^2=144[/tex]
[tex]\\ \rm\Rrightarrow TR=12[/tex]
Now
Apply Pythagorean theorem
[tex]\\ \rm\Rrightarrow x^2=12^2+16^2[/tex]
[tex]\\ \rm\Rrightarrow x^2=144+256[/tex]
[tex]\\ \rm\Rrightarrow x^2=400[/tex]
[tex]\\ \rm\Rrightarrow x=20[/tex]
