Question

If sec a = 2/root 3 and a +b =90 Find cosec b

Answer 1

Given Sec A=2/ root 3 Or Sec A= sec 30 So A= 30 degree Now A+B = 90 Or 30+B = 90 Hence B= 90-30=60 cosec B = cosec 60 degree = 1/2

Answer 2

Answer:

Sec A=2/root3

A=30

A+B=90

So B=60

Cosec B= 1 / SinB

  1/sin60

1/(root3/2)

= 2/(root3)
