A) \[156{}^\circ \]
B) \[165{}^\circ \]
C) \[145{}^\circ \]
D) \[150{}^\circ \]
Correct Answer: A
Solution :
\[\angle A+\angle B+\angle C=180{}^\circ \] \[112{}^\circ +24{}^\circ +x=180{}^\circ \] \[x=180{}^\circ -136{}^\circ =44{}^\circ \] Then, \[2\angle A-(\angle B+\angle C)\] \[2\times 112{}^\circ -(24+44)=224{}^\circ -68=156{}^\circ \]You need to login to perform this action.
