15sinA = 12 . find cos B sec B tan B cosec B

15sinA = 12.
SinA = 12/15
o/h = 12/15
Now find the third side using Pythagoras Theorem.
Then substitute their values in the place of cosB, secB, tanB, cosecB.
And then find the answer.
Sorry. I don't know how to put root sign. That is why I gave an answer like this.
Hope this helped.
Glad to help you.
