If a + b = 90 degree and sec a= 5 / 3 then find the value of cosec b

Answer» Sorry sorry i think it is cosec A
sec a=5/3a+b =90 so b=90-acosec b =cosec(90-a)=sec a=5/3\xa0
sec a=5/3......h^2=p^2+b^2......5^2=p^2+3^2.....25=p^2+9.......p=4....... cosec=h/p.......so cosec=5/4
How please explain ??
5/3.........
