Disprove?

A B n C r angles of a triangle

any one pleease help

ny hint ?

hmn... cn we prove ny inequality for cos a + cos b + cos c

i like this question

@ashwinjohn3 That doesn't count as a proof. =/

@ParthKohli Then prove it by Mathematical induction.....

can you use the law of cosines /

but A , B n C r angles of a triangle.

How can each angle be pi/2 ? A + B + C = 180 @satellite73 sir

(its a three not a two)

Sorry :(

But can this hep us to proceed to get the proof ?

\[A = x, B = 90 - x, C = 90\]

but this proof assumes that the triangle is right angled, which may not be the case.

i dont think we can assume a right angle

Oh, well.

yeah right we shall assume for any triangle

but we are also to prove for "equal to" condition

@mathslover \( n < r\) automatically satisfies \(n \le r\).

oh.. right
