A) \[\Delta ABD\] and \[\Delta ACX\]are similar
B) \[\angle BAD<\angle ACD\]
C) \[AC=CX\]
D) \[\angle ADB>\angle DXC\]
Correct Answer: A
Solution :
In \[\Delta DCX\] CD = CX (Given) \[\angle 3=\angle 4\] (opposite angle of same sides) But \[\angle 3=\angle 5\] So, \[\angle 4=\angle 5\] In \[\Delta ABD\] and \[\Delta ACX,\] \[\angle 1=\angle 2\] (Given) \[\angle 4=\angle 5\] \[\angle B=\angle ACX\] (rest angle) \[\therefore \] \[\Delta ABD\tilde{\ }\Delta ACX\]You need to login to perform this action.
