Answer:

Step-by-step explanation:

Here...cosec(A) =2 means h/p=2

Here..h=2 and p=1 then according to Pythagoras theorem b=1

According tp question

[Cot(A)+sin(A)/1+cos(A)

= b/h+p/h to whole divided by 1+b/h

=(b+p)÷h whole divided by (h+b)÷h

= h gone by h...and reminder will be ( b+p)÷(b+h)

now putting the value of b,p,&h

= (1+1)÷(1+2)

=2÷3

=2/3 answer
