()123 $1. In a triangle ABC, a, b and c are the sides of the triangle satisfying the relation r1 + r2 = r3-r then the perimeter of the triangle 2ab a +b-c ab a +c-b ab a-b-c bc b+c-a 62. In ?ABC, which is not right angled, if p = sinA sinB sinc and q = cosA cosB cosc. Then the equation having roots tanA, tanB and tanC is (1) qxs_px® + (1+4)x-p=0 (2) qx3 + 2px" + qx-p=0 (3) qxs_ px2 + (2 + q)x + pq = 0 (4) qxs_px2 + qx + p = 0

Value of x in the equations px^(2) + qx+r =0 is :
