  1. Answer:

    here given cosθ+secθ=4…(i)

    Step-by-step explanation:

    on squaring eqn. i both side, we get

    cos²θ+sec²θ+2×cosθ×secθ=16

    =>cos²θ+sec²θ+2=16

    =>cos²θ+sec²θ=14.

    plz mark me as brainliest..

  2. Step-by-step explanation:

    [tex] \cos \alpha + \sec\alpha = 4 \\ { \cos }^{2} \alpha + { \sec }^{2} \alpha = 16[/tex]
