secA=13/5 ,show that 2sinA-3cosA/4sinA-9cosA=3 |
| Answer» Given that SecA=13/5. Then we know that Sec=hypotenius/Base, I.e,13/5Then we find perpendicular =12Thus, 2 sinA - 3cosA /4sinA -9cosA =3 {(2 ✖ 12/13 - 3 ✖ 5/13)/(4 ✖ 12/13 - 9 ✖ 5/13)} = 3or. {24 -15/48-45}=3 or. { 9/3}= 3Or. 3=3 Hence LHS=RHS | |
