The correct answer is:

CHECK THE SOLUTION.

→ (q), → (p), → (s), → (r)

Sol.  2B = A + C ⇒ B = and A + C =

 b 2 = ac ⇒ sin 2 B = sin A.sin C ⇒ sin A sin C =

⇒ cos(A – C) – cos (A + C) =  A + C =

⇒ cos(A – C) = 1 ⇒ A = C = = B ⇒ a = b = c ∴ = 1

 a 2 = b 2 + c 2 and 2R = a ∴ = = 8

 Δ = bc sin A ⇒ Δ = .9. sin A = ×  a = 2

∴ 2R Δ = 9

 a = 5, b = 3 and c = 7

and because we know that

b cos C + c cos B = a

∴ 3 cos C + 7 cos B = 5
