Let (A, B ) and (C ) be three angles of a ( A B C ) such that ( A+ B+ C= 3 2 ), then the ( A B C ) is

Options

  1. AEquilateral
  2. BRight angled
  3. CIsosceles but not equilateral
  4. DScalene

Correct answer

A. Equilateral

Step-by-step solution

Given, ( A+ B+ C= 3 2 ) Above equation is possible only for (A=B=C= 3 ) ( A B C ) is equilateral, Hence, option (a) is correct.
