Question

Find the equation of A straight line which cuts off an intercept 5 units.on negative y axis.an makes an angle 120 with the positive x axis.

​

Answer 1

$<b> <u> <i> Heya!!</b> </u> </i>$

______________________________________________________________

$<b> <u>Straight Lines </b> </u>$

→ We are given that ,

★$<b> m = 120° </b>$

=> m = tan ∅

•°• Tan ( 90° + 30°)

$= > - \sqrt{3}$

Also we are given that , $<b> c = -5 </b>$

Putting these values in $<u> y = mx + c </u>$

$= > y = - \sqrt{3} x - 5 \\ \\ = > \sqrt{3} x + y + 5 = 0$

•°• Required Equation :-$<b> <u> <i> √3x + y + 5 = 0 </b> </u> </i>$
