A) \[235{}^\circ \]
B) \[215{}^\circ \]
C) \[195{}^\circ \]
D) \[225{}^\circ \]
Correct Answer: B
Solution :
\[a=75{}^\circ +40{}^\circ =115{}^\circ \] \[b=60{}^\circ +40{}^\circ =100{}^\circ \] (angle opposite to \[40{}^\circ \] is equal to\[40{}^\circ \]) \[a+b=115{}^\circ +100{}^\circ =215{}^\circ \]You need to login to perform this action.
