A) \[\angle A={{80}^{o}}\] and \[\angle C={{35}^{o}}\]
B) \[\angle EDB=\] and \[{{120}^{o}}\]
C) \[{{160}^{o}}\] and \[{{70}^{o}}\]
D) \[{{115}^{o}}\] and \[\Delta ABC\]
Correct Answer: A
Solution :
We know that angle in a semicircle is a right angle. Hence,\[\angle 1=\angle 2\] Also \[\angle 3=\angle 5\] \[{{180}^{o}}\] \[\angle 1+\angle 3={{180}^{o}}\] (\[\angle 5+\angle 2={{180}^{o}}\]\[1||m||n\])You need to login to perform this action.
