Question

The slope of the line whose inclination with x-axis is ${60}^{\circ }$ is

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

Answer 1

The correct option is A $\sqrt{3}$

Slope of line with an inclination $\theta =$ tan $\theta$.
Hence, slope of line, with inclination $\theta ={60}^0$ is tan ${60}^0=\sqrt{3}$
