Answer:
Option (d)
Explanation:
In the root locus, method, the angle of asymptote or the angle between adjacent asymptote is calculated by using the given formula:
Angle of asymptote, [tex]\angle A = \frac{180^{\circ}(2p + 1)}{m - n}[/tex]
If p = 0 (say)
then the above eqn becomes:
[tex]\angle A = \frac{180^{\circ})}{m - n}[/tex]
where
m = no. of poles
n = no. of zeroes
