Question 1111025
.
<pre>
We are given {{{alpha}}} = {{{pi/7}}},

angle {{{theta}}} is such that  {{{pi/2}}} < {{{theta}}} < {{{2pi}}}  and  {{{sin(alpha)}}} = {{{sin(theta)}}}.


Then  {{{theta}}} = {{{pi - pi/7}}} = {{{(7pi)/7 - pi/7)}}} = {{{(6pi)/7}}}.


<U>Answer</U>.  {{{theta}}} = {{{(6pi)/7}}}.
