A) 4.5cm
B) 4cm
C) 5cm
D) 6.5cm
Correct Answer: A
Solution :
\[{{40}^{o}}\] DA, OM and CB are perpendicular to AB. We have\[{{50}^{o}}\] Now, AC and DB are two transversals to these parallel lines. The result of proportional intercepts on parallel lines. We have, \[{{55}^{o}}\] \[{{108}^{o}},{{72}^{o}}\]\[{{72}^{o}},{{36}^{o}}\]\[{{100}^{o}},{{80}^{o}}\] \[{{144}^{o}},{{36}^{o}}\] \[\angle P=\angle R={{100}^{o}}\]You need to login to perform this action.
