  1. If   tanθ =
    8
    , the value of
    1 − sinθ
      is :
    151 + sinθ
    1. 1
      5
    2. 2
      5
    3. 3
      5
    4. 0
Correct Option: C

tanθ =
8
15

∴  sec2θ – tan2θ = 1
⇒  sec2θ = 1 + tan2θ
= 1 +
8
2
15

= 1 +
64
=
225 + 64
=
289
225225225


=
1
sinθ
= secθ − tanθ
cosθcosθ

=
17

1515

=
17 − 8
=
9
=
