according to trigonometry identities,
sec (90-b) = cosec b
sec (90-b) = cosec b

A + B = 90o
A = 90o - B
sec A = 5/3
Also
sec A = sec (90o - B) (because A = 90o - B)
= cosec B
= 5/3
Hence, cosec B will also be 5/3
A = 90o - B
sec A = 5/3
Also
sec A = sec (90o - B) (because A = 90o - B)
= cosec B
= 5/3
Hence, cosec B will also be 5/3
