Step-by-step explanation:
If one of the line is parallel to y-axis then the angle between two straight lines is given by tan θ = ±1/m where 'm' is the slope of the other straight line. If the two lines are a1x + b1y + c1 = 0 and a2x + b2y + c2 = 0, then the formula becomes tan θ = |(a1b2 - b1a2)/(a1a2 + b1b2)|
