Question

if 16 cos theta=7 then sec theta=?​

Answer 1

hey mate your answer is here ⬇️⬇️⬇️

Secθ+tanθ=7

∵, sec²θ-tan²θ=1

or, (secθ+tanθ)(secθ-tanθ)=1

or, 7(secθ-tanθ)=1

or, secθ-tanθ=1/7

Answer 2

Answer:

16/7

Step-by-step explanation:

16 cos theta = 7

cos theta = 7/16

sec theta = 1/cos theta

= 16/7

sec theta = 16/7
