Answer 2

Answer:

2

Step-by-step explanation:

if cosec A=2

then find the value of cot A+(sinA/(1+cosA))

cosecA=2=1/sinA

sinA=1/2

A=30°

cotA+(sinA/(1+cos))

cot30°+(sin30°/(1+cos30°))

√3+((1/2)/(1+√3+2)

√3+((1/2)/((2+√3)(√2)

√3+((1/2)/((2+√3)/2)

√3+(1/(√2+√3))

(2√3+3+1)/(2+√3)

(2√3+4)/(2+√3)

(2(2+√3)/(2+√3))

=2
