The sides of a triangle are , and 1+ for some 0 2 , then the greatest angle of a triangle is

Options

  1. A3
  2. B2 3
  3. C6
  4. D5 6

Correct answer

B. 2 3

Step-by-step solution

a = , b = and c = 1+ Since 1+ is greater than and . C is the greatest angle, aligned & C & & = a^2+b^2-c^2 2 a b & & =- 1 2 = 120^ & C aligned
