Suppose

a, b, c

are the lengths of three sides of a

\triangle A B C, a > b > c, 2 b=a+c

and

b

is a positive integer. If

a^2+b^2+c^2=84

, then value of

b

View answer and explanation

Correct option: C

Option C (5) is correct because using the given conditions

2b = a+c

and

a^2 + b^2 + c^2 = 84

, and the triangle inequality, we can deduce that b = 5.
