~~~~~~~~~~~~~~~~~~~~~~~~



&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;@mananth incorrectly read and interpreted the problem,

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;so his answer is irrelevant and incorrect.



<pre>
25 = 16 - t^2

t^2 = 16 - 25

t^2 = -9

t = {{{sqrt(-9)}}} = +/- 3*i,  where i = {{{sqrt(-1)}}}  is the imaginary unit.    <U>ANSWER</U>

Solved.
