-hey everybody!:)
you can answer here. ​

Answer 1

Given:

0° < θ < 90°

To find:

The value of Sec (0°)

Solution:

It is known that the value of Cos (0°) is 1 and also,

$Cos\theta=\frac{1}{Sec\theta}$

$Sec\theta=\frac{1}{Cos\theta}$

i.e., Sec (θ) is the reciprocal of Cos (θ).

When $\theta=0$,

$Cos0=1$

$Cos0=\frac{1}{Sec0}$

$Sec0=\frac{1}{Cos0}$

∴ $Sec0=\frac{1}{1}=1$

The value of Sec(0°) is 1.

Hence, option (c) is the correct answer.

The value of Sec(0) = 1 and the correct answer among the options is option (c).
