If theta is the acute angle butween the pair of lines represented by 3x^(2)-8xy+4y^(2)=0 then (2cos theta+3sin theta)/(4sin theta+5cos theta) is

If theta is the acute angle between the pair of the lines x^(2)+3xy4y^(2)=0 then sin theta=

If theta is the acute angle between the pair of lines 5x^2-8xy-y^2=0 then find cos theta

4 sin 5 theta cos 3 theta sin 2 theta

If theta is the acute between the pair of lines x^(2)+3xy-4y^(2)=0 then sin theta=

If the angle 2 theta is acute, then the acute angle between the pair of lines x^(2)(cos theta-sin theta)+2 x y cos theta+y^(2)(cos theta+sin theta)=0 is

If theta is the parameter, then the family of lines represented by (2cos theta+3 sin theta)x+(3 cos theta-5sin theta)y-(5cos theta-7sin theta)=0 are concurrent at the point
