A) \[{{10}^{o}}\]
B) \[{{40}^{o}}\]
C) \[{{50}^{o}}\]
D) None of these
Correct Answer: C
Solution :
We have \[\angle ACB\] (Linear pair) \[{{42}^{o}}\] So \[\angle ACB={{65}^{o}}\] (\[\angle ABC\] \[{{25}^{o}}\]) \[{{35}^{o}}\] (Linear pair) \[PQ||RS\] \[{{60}^{o}}\] \[{{75}^{o}}\] In \[{{105}^{o}}\] \[{{85}^{o}}\] [A.S.P] \[{{60}^{o}}\] \[\angle BAC={{45}^{o}}\]You need to login to perform this action.
