Question

Slope of a line which makes an angle ${60}^{\circ }$ with the positive direction of the X-axis is _____.

• A. 1
• B. 0.0
• C. $\sqrt{3}$
• D. $\sqrt{2}$

Answer 1

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

Slope of a line which makes an angle $\theta$ with the positive direction of the X-axis is $m=tan\theta$.
$\therefore$Slope of the line which makes an angle ${60}^{\circ }$ with the positive direction of the X-axis is $m=tan{60}^{\circ }$ = $\sqrt{3}$
