Solution

The correct option is C Statement-1 is True, Statement-2 is False
STATEMENT- 2 Let a = -a', b = -b'
a+b2=[a+b2]ab=ab
STATEMENT - 2 is false.
STATEMENT - 1 Equation of tangent is xcosθa+ysinθb=1
The intercepts are a secθ and bcosecθ
Length of intercept =a2sec2θ+b2cosec2θ
a2sec2θ+b2cosec2θ=a2+b2+a2tan2θ+b2cot2θ(a+b)2
