cosec A =2 then sinA/1+cosA​

Answer 1

Answer look at the image

Step-by-step explanation

Look at the image

Answer 2

Answer:

Step-by-step explanation:

cosecA=2

cosecA=h÷p

then

h=2 and p=1

using pythagoras theorem

b=√h²_b²

  =√2²_1²

 =√4_1

∴b=√3

NOW

sinA+cosA

=p÷h+b÷h

=1÷2+√3÷2

=(1+√3)÷2
