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
