A) \[48{}^\circ \]
B) \[52{}^\circ \]
C) \[72{}^\circ \]
D) \[50{}^\circ \]
Correct Answer: C
Solution :
Draw a line UR parallel to QP \[\angle PQR=\angle QRU=x\] \[\angle QRS+\angle SRU=x\] \[\angle SRU=x-36{}^\circ \] \[\angle TSR+\angle SRU=180{}^\circ \] \[2x+x-36{}^\circ =180{}^\circ \] \[3x=180{}^\circ +36{}^\circ =216\] \[x=72{}^\circ \]You need to login to perform this action.
