Question

find the slope of a line which makes an angle of 90with positive direction of x axis​

Answer 1

Answer:

line is making an angle 90 with positive direction of x axis

that means line is parallel to y axis

So, its slope becomes tan90

= 1/0

= infinity

Answer 2

Answer:

Hey !!

If a line makes an angle of 30° with the positive direction of the y-axis measured anticlockwise, then the angle made by the line with the positive direction of the x-axis measured anticlockwise is 90° + 30° = 120°

Thus, the slope of the given line is

tan 120° = tan (180° - 60°)

= tan 60°

FINAL RESULT = -√3
