A) \[{{35}^{{}^\circ }}\]
B) \[{{60}^{{}^\circ }}\]
C) \[{{80}^{{}^\circ }}\]
D) \[{{100}^{{}^\circ }}\]
Correct Answer: A
Solution :
(a): \[\angle RPT={{55}^{{}^\circ }}\] \[\angle RPQ={{90}^{{}^\circ }}\] (Angle of semi circle) \[\angle TPS={{180}^{{}^\circ }}\] \[\therefore \] \[\angle SPQ={{180}^{{}^\circ }}-{{55}^{{}^\circ }}-{{90}^{{}^\circ }}={{35}^{{}^\circ }}\]You need to login to perform this action.
