Top vertex of triangle   Q((a/2),((a(√3))/2))  slope of line  (((a(√3))/2)/((a/2)−x))=((((a(√3))/2)+a)/((a/2)−y))  ⇒ (a/2)−y=(2/(a(√3)))(((a(√3))/2)+a)((a/2)−x)  y=(a/2)−(1+(2/( (√3))))((a/2)−x)
$${Top}\:{vertex}\:{of}\:{triangle}\: \\ $$$${Q}\left(\frac{{a}}{\mathrm{2}},\frac{{a}\sqrt{\mathrm{3}}}{\mathrm{2}}\right) \\ $$$${slope}\:{of}\:{line} \\ $$$$\frac{\frac{{a}\sqrt{\mathrm{3}}}{\mathrm{2}}}{\frac{{a}}{\mathrm{2}}−{x}}=\frac{\frac{{a}\sqrt{\mathrm{3}}}{\mathrm{2}}+{a}}{\frac{{a}}{\mathrm{2}}−{y}} \\ $$$$\Rightarrow\:\frac{{a}}{\mathrm{2}}−{y}=\frac{\mathrm{2}}{{a}\sqrt{\mathrm{3}}}\left(\frac{{a}\sqrt{\mathrm{3}}}{\mathrm{2}}+{a}\right)\left(\frac{{a}}{\mathrm{2}}−{x}\right) \\ $$$${y}=\frac{{a}}{\mathrm{2}}−\left(\mathrm{1}+\frac{\mathrm{2}}{\:\sqrt{\mathrm{3}}}\right)\left(\frac{{a}}{\mathrm{2}}−{x}\right) \\ $$
