In a triangle

PQR,\;\angle R = \frac{\pi }{2}

. If

\tan \left( {\frac{P}{2}} \right)

and

\tan \left( {\frac{Q}{2}} \right)

are the roots of

a{x^2} + bx + c = 0,\;a \ne 0

then

View answer and explanation

Correct option: C

c = a + b

Option C (

c = a + b

) is correct because it is derived from the trigonometric identity of

\tan(\frac{P}{2} + \frac{Q}{2})

and the given condition that

\angle R = \frac{\pi}{2}
