15 cot A = 8
cot A = 8 / 15
tan A = 15 / 8
tan^2 A = 225 / 64
1 + tan^2 A = sec^2 A = 289 / 64
sec A = 17 / 8 OR -17 / 8
1 + cot^2 A = csc^2 A = 1 / sin^2 A = 289 / 225
sin^2 A = 225 / 289
sin A = 15 / 17 OR -15 / 17
cot A = 8 / 15
tan A = 15 / 8
tan^2 A = 225 / 64
1 + tan^2 A = sec^2 A = 289 / 64
sec A = 17 / 8 OR -17 / 8
1 + cot^2 A = csc^2 A = 1 / sin^2 A = 289 / 225
sin^2 A = 225 / 289
sin A = 15 / 17 OR -15 / 17
