A) \[65{}^\circ \]
B) \[110{}^\circ \]
C) \[130{}^\circ \]
D) \[220{}^\circ \]
Correct Answer: B
Solution :
Let the two supplementary angles are \[{{x}^{o}}\] and \[{{180}^{o}}-x\] By hypothesis, \[x-({{180}^{o}}-x)={{40}^{o}}\] or \[2x-{{180}^{o}}={{40}^{o}}\] or \[2x={{220}^{o}}\] or \[x={{110}^{o}}\]You need to login to perform this action.
