A) \[DA\bot AB,\]
B) \[CB\bot AB\]
C) 20
D) \[OM\bot AB\]
Correct Answer: B
Solution :
First, we draw line CE which AB at E Given \[{{30}^{o}}\] and CD = 3 cm And AB = 7cm Now, \[{{80}^{o}}\] \[{{100}^{o}}\] (\[\angle DAC={{54}^{o}}\] \[\angle ACB={{63}^{o}}\]) \[\angle BAC\] \[{{72}^{o}}\] \[{{54}^{o}}\] \[{{27}^{o}}\] Now, in \[{{90}^{o}}\] \[\angle BOD={{120}^{o}}\] \[\angle ACD\] \[{{30}^{o}}\] Now, area of trapezium \[{{40}^{o}}\] \[{{60}^{o}}\] Area \[{{90}^{o}}\]You need to login to perform this action.
