In the figure below (not to scale), `bar(MR )_|_ bar(MP), bar(MQ) _|_ bar(MN)`, and `bar(MS)` is bisector of `/_ RMQ` . If `/_ PMN=50^(@)` , then find the measure of `/_ RMS`. A. `25^(@)`B. `20^(@)`C. `30^(@)`D. `35^(@)`

Answer» Correct Answer - a
(i) Find `/_QMP` using `/_ QMP = /_QMN- /_PMN`.
(ii) Find `/_ RMQ ` using `/_ RMQ= 90^(@)- /_ QMP`.
(iii) Now `/_RMS =(1)/(2) /_ RMQ`
