If 2 is the length of a side of a triangle with its opposite angle ' / 3 ', then the circumradius of the triangle is ......

Options

  1. A2 3
  2. B4 3
  3. C2
  4. D4

Correct answer

A. 2 3

Step-by-step solution

According to the question, a=2 and A= 3 So, by sine Iaw, we have a A =2 R 2 3 / 2 =2 R R= 2 3
