Question 13 Consider the following unity feedback system: R(s) + K(s + 1) 52 +53 + 17.33 C($) The approximate angles of departure of the root locus from the complex poles are: O None of them are correct. O +205 O +180° O 45° O #135°

Question 12 Select the correct statement about the root locus of the following system: R(S) K(s + 1) s2 + 5s + 17.33 C(s) The root locus has two branches and points-0.2 on the real axis belongs to the root locus. o When K goes to +, two branches of the root locus end at-1 and one remaining branch goes to infinity approaching an asymptote. The root locus has three branches and point s--2 on the real axis belongs to the root locus. None of them are correct. For K-0, the root locus begins at s--1 and when K goes to +, two branches go to infinity approaching asymptotes.
