Question

The slope of the line with inclination ${30}^o$ is

• A. $\frac{1}{\sqrt{3}}$
• B. $\frac{1}{2}$
• C. $\frac{\sqrt{3}}{2}$
• D. $1$

Answer 1

Answer: (A)

$\frac{1}{\sqrt{3}}$

Slope of a line with inclination $\theta$ is given by $\tan \theta$
Here, $\theta ={30}^{\circ }$

$\therefore$ Slope of the line with inclination ${30}^{\circ }$ is
$\tan {30}^{\circ }=\frac{1}{\sqrt{3}}$

Hence, option A is correct.
