A) \[95{}^\circ ,\]\[85{}^\circ \]
B) \[108{}^\circ ,\]\[72{}^\circ \]
C) \[130{}^\circ ,\]\[50{}^\circ \]
D) \[105{}^\circ ,\]\[75{}^\circ \]
Correct Answer: C
Solution :
Here, \[a+b=180{}^\circ \]and \[a-b=80{}^\circ \Rightarrow 2a=260{}^\circ \] \[\Rightarrow \] \[a=130{}^\circ \] \[b=180{}^\circ -130{}^\circ =50{}^\circ \] So, \[a=130{}^\circ ,\]\[b=50{}^\circ \]You need to login to perform this action.
