The value of A/b is 2.60Step-by-step explanation:We have cosine formula

c² = a² + b² – 2ab cosC

Here

c = B

a = 6

b = 7

C = 60°

Substituting

B² = 6² + 7² – 2 x 6 x 7 cos60

B² = 43

B = 6.56

b = 7 closest integer to B.

Given that A is area of triangle

A=0.5absinC

A = 0.5 x 6 x 7 x sin60 = 18.19

We need to find

The value of A/b is 2.60
