View answer and explanation
Correct option: A
(2−3)  :23\left( {2 - \sqrt 3 } \right)\;:2\sqrt 3
Option A ((2−3) :23\left( {2 - \sqrt 3 } \right)\,:2\sqrt 3) is correct because the ratio of the in-radius and the perimeter of the right-angled triangle with angles in A.P. is (2−3) :23\left( {2 - \sqrt 3 } \right)\,:2\sqrt 3.
