TS EAMCET · Maths · Properties of Triangles
If the radius of the incircle of a triangle with sides \(5 k, 6 k\) and \(5 k\) is 6 , then the largest angle of that triangle is
- A \(\cot ^{-1}\left(\frac{3}{7}\right)\)
- B \(\tan ^{-1}\left(\frac{24}{7}\right)\)
- C \(\sin ^{-1}\left(\frac{3}{5}\right)\)
- D \(\cos ^{-1}\left(\frac{6}{\sqrt{85}}\right)\)
Answer & Solution
Correct Answer
(B) \(\tan ^{-1}\left(\frac{24}{7}\right)\)
Step-by-step Solution
Detailed explanation
Given, sides of \(\triangle A B C\) is \(5 k, 5 k\) and \(6 k\) respectively, \(A B C\) is an isosceles triangle,…
