A) \[\angle DAC={{54}^{o}}\]
B) \[\angle ACB={{63}^{o}}\]
C) \[\angle BAC\]
D) \[{{72}^{o}}\]
Correct Answer: B
Solution :
Let the angles be 3x, 4x, 5x and 6x. We have \[BD=CD\] [sum of angles of a quadrilateral is equal to \[\Rightarrow \]] \[\frac{AO}{OD}=\frac{2}{1}\] \[AO:OD=2:1\] Difference between greatest and smallest angles \[\angle A,\angle B,\angle C\]You need to login to perform this action.
