Question

The area of the triangle formed by the line x + y = 3 and the angular bisectors of pair of straight lines $x^2-y^2+2y=1$ is

• A. 8 sq.units
• B. 6 sq.units
• C. 4 sq.units
• D. 2 sq.units

Answer 1

The correct option is D 2 sq.units

$x^2-(y-1{)}^2=0$ is given pair of lines
Vertices are (0,1),(0,3),(2,1) ,
Angular bisector is x(y-1) = 0
Area = 2 sq.units
