<U>Answer</U>.  {{{tan(pi/2-theta)}}} = {{{1/tan(theta)}}} = {{{cot(theta)}}} = {{{4/3}}}.



<U>Solution</U>


<pre>
{{{sin(pi/2-theta)}}} = {{{cos(theta)}}}.    It is well known basic identity.


{{{cos(pi/2-theta)}}} = {{{sin(theta)}}}.    It is well known basic identity.



Therefore,  {{{tan(pi/2-theta)}}} = {{{sin(pi/2-theta)/cos(pi/2-theta)}}} = {{{cos(theta)/sin(theta)}}} = {{{1/tan(theta)}}} = {{{4/3}}}.
