Step-by-step explanation:
i. Given, (A, C) = 17, d(B, C) = 6.5 d(A, C) = d(A, B) + d(B, C) …[A – B – C] ∴ 17 = d(A, B) + 6.5 ∴ d(A,B)= 17 – 6.5 ∴ d(A, B) = 10.5 ii. Given, d(P, Q) = 3.4, d(Q, R) = 5.7 d(P,R) = d(P,Q) + d(Q,R) …[P – Q – R] = 34 + 5.7 ∴ d(P, R) = 9.1Read more on Sarthaks.com - https://www.sarthaks.com/848860/answer-the-following-questions-i-if-a-b-c-and-d-a-c-17-d-b-c-6-5-then-d-a-b
