In DeltaABC , In a triangle ABC, angleC=60^(@) and angleA=75^(@) . If D is a point on AC such that the area of the DeltaBAD is sqrt(3) times the area of the DeltaBCD , find the angleABD .

In /_\ABC , a = 3, b = 4, C= 90^@ and D is a point on AB such that angleBCD= 30^@ . Find the length of CD.

If A B , B C a n d C D are equal chords of a circle with O as centre and A D diameter, then /_A O B= 60^0 (b) 90^0 (c) 120^0 (d) none of these

In the figure, ABC is a triangle in which /_C=90^(@) and AB=5cm . D is a point on AB such that AD=3cm and /_ACD=60^(@) . Then the length of AC is
