A) \[23{}^\circ ,\,\,67{}^\circ \]
B) \[51.5{}^\circ ,\,\,29.5{}^\circ \]
C) \[50{}^\circ ,\,\,30{}^\circ \]
D) \[67.5{}^\circ ,\,\,22.5{}^\circ \]
Correct Answer: D
Solution :
In\[\Delta TOR,\] \[\angle OTS=\angle ROT=x\] \[\angle ORT=45{}^\circ \] \[x+x+45{}^\circ =180{}^\circ \] \[x=\frac{135{}^\circ }{2}=67.5{}^\circ ;\,y=90-x=22.5{}^\circ \]You need to login to perform this action.
