Question

if cotB = 12/5 then the value of cosec B

Answer 1

Answer:

13 /5 is ans

1 st find sin then cosec is inverse of sin

Answer 2

answer:

cosecB=13/5

step by step:

since cot = b/p

so b=12 ans p = 5

using PGT

H²=B²+P²

H =√12²+5²

= √144+25

=√169

H=13

since cosecB=H/P

so

cosecB=13/5
