Answer 2

Answer:

Equation of lines passing through origin and having 30° and 60°

Angles with x-axis are

$y=tan \: 30∘x     and     </p><p></p><p>y= tan \: 60∘</p><p>y= \: 3x     and     </p><p>y=3x</p><p></p><p>$

$So, \: pair \: of  \: straight \: lines \: of y=3x  and   y=3x is</p><p></p><p>(y−3x)(y−3x)=y2+x2−3xy−3xy=0</p><p></p><p>⇒3(x2+y2)−4xy=0</p><p></p><p>⇒3(x2+y2)=4xy</p><p></p><p>$
