Question 264317
<pre>
angle1              180-v=116
angle2, base         v
angle3, base         v
SUM                 180
</pre>

{{{v=64}}}
but this assigning fails.
{{{v+v+116=180}}}
{{{64+64+116=180}}}
FALSE!


You could try to assign which angle to be variable, differently and find what happens.
