A) \[120{}^\circ \]
B) \[40{}^\circ \]
C) \[20{}^\circ \]
D) \[70{}^\circ \]
Correct Answer: D
Solution :
Diameter = OP and AP line touches the circle. \[\therefore \] \[\angle OPA\,=90{}^\circ \] \[\therefore \] \[x=180{}^\circ -(90{}^\circ +20{}^\circ )=180{}^\circ -110{}^\circ =70{}^\circ \]You need to login to perform this action.
