1.)5 cosø = 6 sinø
sinø/cosø= 5/6
tanø = 5/6
2.) sinø = 5 cosø/6
Put in the (ii) part
{12 (5 cosø/6) - 3(cos ø) }/ { 12 (5 cosø/6) +3(cos ø) }
=> { 10cosø-3 cosø} / { 10cosø+3 cosø}
=> 7 cosø/13cosø
=> 7/13
sinø/cosø= 5/6
tanø = 5/6
2.) sinø = 5 cosø/6
Put in the (ii) part
{12 (5 cosø/6) - 3(cos ø) }/ { 12 (5 cosø/6) +3(cos ø) }
=> { 10cosø-3 cosø} / { 10cosø+3 cosø}
=> 7 cosø/13cosø
=> 7/13
thanx frnd
