Question

( Rightarrow quad sec A=-frac{5}{4} Rightarrow ) An abtuse
3) ( cos A=-frac{4}{2} )
[
begin{aligned}left(sin eta_{b}right) & tan A+operatorname{cosec} A=-frac{3}{4}+frac{5}{3}=frac{11}{12} operatorname{reat} & tan A cdot operatorname{cosec} A=-frac{3}{4} cdot frac{5}{3}=frac{-5}{4} end{aligned}
]
2) ( x^{2}-left(frac{11}{12}right) x-5=0 )
( Rightarrow quad 12 x^{2}-11 x-15=0 )
(9) And

# d. None of these If ABCD is a convex quadrilateral such that 4 sec A + 5 = 0, then the quadratic equation whose roots are tan A and cosec Ais a. 12x² - 113 - 15 = 0 b. 12x² + 11 - 15 = 0 c. 12x2 - 29x + 15 = 0 d. None of these
