1.	If `3tanA+4=0`, then the value of `2cotA-5cosA+sinA` is equal toA. `23/10ifpi/2ltAltpi`B. `23/10if(3pi)/2ltAlt2pi`C. `(-53)/10ifpi/2ltAltpi`D. `-53/10if(3pi)/2ltAlt2pi`
Answer» Correct Answer - A::D We have `tanA=-3/4` If A lies in `2^(nd)` quadrant, then `sinA=4/5,cosA=(-3)/5,and cotA=(-3)/4` If lies `2^(nd)` quadrant, then `sinA=(-4)/5,cosA=(3)/5,and cotA=(-3)/4`
