A) \[80{}^\circ \]
B) \[135{}^\circ \]
C) \[100{}^\circ \]
D) \[110{}^\circ \]
Correct Answer: C
Solution :
(c): By property of isosceles \[\Delta le,\]the two \[\angle les\]shown are \[50{}^\circ \] \[\Rightarrow \,\,\angle x=180{}^\circ -50{}^\circ -50{}^\circ =80{}^\circ \] \[\Rightarrow \,\,\angle RQT=180{}^\circ -80{}^\circ =100{}^\circ \]You need to login to perform this action.
