Let the equations of side BC and the internal angle bisector of angle B of 
ABC are 2x -5y + a = 0 and y + x = 0 respectively. If A = (2,3),then the value of a is equal to
Text Solution
Verified by ExpertsThe correct answer is:
D
-4
Reflection of A (2,3) about line y + x = 0 is A (-3, -2) which lies on side BC
2 (-3) - 5 (-2) + a = 0 
a = -4
