Answer 1

Y_0 locate poles & zeros poles at s = 0, 0, -20 zero at s = -10 y_0 find the roots on Real Axis choose at least point on Real axis b/w s = 0 & s = -10 y_0 the right of this point the total number of real poles & zeros two, which is an even number, hence true real axis b/w s = 0, & s = -10 will not be apart of foot lowest B/W s = -10 && s = -20, total no. of real poles & zeros three which is an add number. Hence it will be part of Root loess y_0 fin asymptotes & centroid Angle of asymptotes = plusminus 180 degree (2q + 1)/n - m q = 0, 1, 2, .... N - m n = 3, m = 1 q = 0, 1, 2 when q = 0, 1, 2 when q = 0, angle = plusminus 180/2 = plusminus 90
