Question

If $\sec \theta =1$; $0\le \theta <{12}^{\circ }$, then the value of $\theta$ is

• A. $5^{\circ }$
• B. $0^{\circ }$
• C. $1^{\circ }$
• D. $2^{\circ }$

Answer 1

The correct option is B $0^{\circ }$

$\sec \theta =1$
We know that $\sec 0^{\circ }=1$.
Therefore, $\theta =0^{\circ }$

So, option $B$ is correct.
