Question

Find the angle between the lines x + 1 = 0 and √3x + y - 3 = 0. This question is from Straight Lines. Please help.

Answer 1

Step-by-step explanation:

When written in form y=mx+c, m= slope of line

For L1: y=−3x−1=m1=−3

For L2:o.y=x+1⇒y=0x+01⇒m2→∞

Slope between lines =∣∣∣∣∣1+m1m2m2−m1∣∣∣∣∣=tanθ

θ=Angle ⇒θ=tan−1⎝⎜⎜⎛∣∣∣∣∣∣∣∣m1+m211−m2
