Question

In a triangle PQR, ∠R = π/2, if tan (P/2)and tan(Q/2) are the roots of the equation ax² + bx + c = 0(a ≠ 0), then

(a) a + b = c

(b) b + c = a

(c) a + c = b

(d) b = c

Answer 1

Correct option: (a) a + b = c

Explanation:

It is given that tan (P/2)and tan (Q/2) are the roots of the quadratic equation
