.
If your equation is &amp;nbsp;sin(3A) = sin(2A) &amp;nbsp;then


3A + 2A = {{{pi}}},


5A = {{{pi}}},


A = {{{pi/5}}}, &amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;or


A = {{{180^o/5}}} = 36°.


--------------------------------------------------


O! &amp;nbsp;There is one more solution: &amp;nbsp;A = 0, &amp;nbsp;but it is not so interesting.


A = 180° is the solution also, by the way.
