Question 1122326
Let {{{ alpha }}} = the 3rd angle
{{{ 30 + 15/60 + 33 + 12/60 + alpha = 360 }}}
{{{ 63 + 27/60 + alpha = 360 }}}
{{{ alpha = 360 - 63 - 27/60 }}}
{{{ alpha = 297 - .45 }}}
{{{ alpha = 296.55 }}}
———————————
Angle {{{ alpha }}} is opposite the known sides,
so I can say:
{{{ 44.32/sin( 296.55 ) = b/sin( 30.25 ) }}}
{{{ 44.32/-.8945 = b/.50378 }}}
{{{ -49.5472 = b/.50378 }}}
{{{ b = -24.961 }}}
————————————
{{{ -49.5472 = c/sin( 33.2 ) }}}
