The line passes through(1,0) and(-2,√3) makes an angle of ___ with thex-axis.
60°
120°
150°
135°
Find the angle of the line from x-axis
The slope of the line passing through(1,0) and(-2,√3) =m=y2–y1x2–x1
so, the slope of the given line =m=3-0-2-(1)=-13
⇒m=tanθ=-13⇒θ=150°
Hence, the correct option is OptionC.
A line passes through a point A (1, 2) and makes an makes an angle of 60∘ with the x-axis and intersects the line x + y = 6 at the point P. Find AP.
Find the equation of the straight line which passes through the point (1, 2) and makes such an angle with the positive direction of x-axis whose sine is 35.
