A, B

and

C

are angles of anyone of the triangle such that

\tan A+\tan B+\tan C=100

. Then,

View answer and explanation

Correct option: A

There exist exactly three non-similar isosceles triangles

Option A (There exist exactly three non-similar isosceles triangles) is correct because the equation

x^3-50 x^2+50=0

has three distinct real roots, implying three different values for angle A.
