`A(1,3)and c(-2/5,-2/5)`are the vertices of a `DeltaABCand`the equation of the angle bisector of `/_ABC` is `x+y=2.` Then the value of B is. (A) (3/10, 17/10) (B) (17/10, 3/10) (C) (-5/2, 9/2) (D) (-1,1)

A

(A) (3/10, 17/10)

B

(B) (17/10, 3/10)

C

(C) (-5/2, 9/2)

D

(D) (-1,1)

Text Solution

Verified by Experts

The correct Answer is:
C
Vertex B is the point of intersection of 7x+3y+4=0 and x+y-2, i.e., `B-=(-5//2, 9//2)`.
