If in a A B C, s(s-a)=(s-b)(s-c) , then

Options

  1. AA= 4
  2. BB= 3
  3. CA= 2
  4. DB= 2

Correct answer

C. A= 2

Step-by-step solution

Given, A B C and aligned s(s-a) & =(s-b)(s-c) A 2 & = (s-b)(s-c) b c = s(s-a) b c aligned Also, A 2 = s(s-a) b c ^2 A 2 = s(s-a) b c array ll and ^2(A / 2)= s(s-a) b c & ^2(A / 2)= ^2 A 2 & ^2(A / 2)=1 (A / 2)=1 & (A / 2)= ⁻¹ 1=( / 4) A=(2 / 4)= 2 & A= 2 array
