A) \[{{40}^{{}^\circ }}\]
B) \[{{10}^{{}^\circ }}\]
C) \[{{20}^{{}^\circ }}\]
D) \[{{30}^{{}^\circ }}\]
Correct Answer: C
Solution :
(c): \[\angle PGH={{70}^{{}^\circ }}\Rightarrow \angle QGH={{110}^{{}^\circ }}\] \[\angle QHD={{130}^{{}^\circ }}\Rightarrow \angle CHQ={{50}^{{}^\circ }}\] \[\therefore \]\[\angle x+{{110}^{{}^\circ }}+{{50}^{{}^\circ }}={{180}^{{}^\circ }}\] \[\Rightarrow \]\[\angle x={{20}^{{}^\circ }}\]You need to login to perform this action.
