A) \[{{85}^{o}}\]
B) \[{{60}^{o}}\]
C) \[\angle BAC={{45}^{o}}\]
D) \[\angle BED={{120}^{o}}\]
Correct Answer: C
Solution :
We have, \[{{65}^{o}}\] (\[{{105}^{o}}\] \[{{95}^{o}}\]) In \[{{85}^{o}}\] \[\angle A={{60}^{o}},\] \[CE||BA\] \[\angle ECD={{65}^{o}}\] \[\angle ACB=\] \[{{60}^{o}}\] \[{{55}^{o}}\] \[{{70}^{o}}\] (Alternate interior angles)You need to login to perform this action.
