A) \[{{75}^{o}}\]
B) \[~105{}^\circ \]
C) \[~60{}^\circ \]
D) \[30{}^\circ \]
Correct Answer: A
Solution :
The sum of supplementary angles is \[{{180}^{o}}.\] According to the question, \[180-x-x=30\] \[\Rightarrow 180-2x=30\] \[\Rightarrow \]\[2x=180-30=150\] \[x=150+2={{75}^{o}}\]You need to login to perform this action.
