If in a triangle A B C , with usual notations, the angles are in A.P. and b : c = 3 : 2 , then angle. A =

Options

  1. A30^
  2. B60^
  3. C75^
  4. D45^

Correct answer

C. 75^

Step-by-step solution

Since the angles are in A.P., therefore B=60^ By sine rule, aligned & b c = B C 3 2 = 3 2 C C=45^ & A=180^ -60^ -45^ =75^ aligned
