WebCalcule AC. 28. En un triángulo ABC se inscribe una = 7 3 circunferencia tangente a los lados AB, BC y AC en los puntos P, Q y T respectivamente. La prolongación de PQ intercepta a la prolongación de AC en R. Si AP=m y CQ=n (m>n), entonces CR mide: n(m + 2n) m(m + n) Web-10i - 2j -10k. Vector AB = p.v.of B - p.v.of A. = (-10i - 2j -10k) - (-4i + pj - 6k). Vector AB = -6.i - (p+2).j -4.k. In right angled triangle OAB , vector OA and vector AB are perpendicular to each other, therefore :- (Vector OA) . (vector AB) = 0. or, ( -4.I +p.j -6.k). {-6.i - (p+2).j - 4.k} = 0. or, 24 - p. (p+2) + 24 = 0 .
