Question

The inclination of a line is ${30}^{\circ }$ then the slope of the line is _________

• A. 0
• B. 1
• C. $\sqrt{3}$
• D. $1/\sqrt{3}$

Answer 1

The correct option is D $1/\sqrt{3}$

Slope of a line of inclination $\theta$ is $tan\theta$
So the slope of the line with inclination ${30}^0$, is $tan30=\frac{1}{\sqrt{3}}$
