[" c) The altitude AD of "/_ABC" ,in which "/_A" is obtuse,is "10cm" .If "BD=10cm&CD=10vv3],[" cm.determine "/_A" ."]

The altitude AD of a Delta ABC, in which /_A obtuse and,AD=10cm* If BD=10cm and CD=10sqrt(3)cm, determine /_A

The altitude A D of a Delta A B C , in which /_A obtuse and, A D=10c mdot If BD=10cm and CD= 10sqrt(3)c m , determine /_Adot

In Fig.4.41,AD is the bisector of /_A. If BD=4cm,DC=3cm and AB=6cm determine AC.( FIGURE )

ABCD is a trapezium in which AB ||CD, AB =20cm, BC =10 cm, CD =10 cm and AD =10 cm . Find /_ADC

In ABC, the bisector of /_A intersects BC in D. If AB=18cm,AC=15cm and BC=22cm, find BD

In triangle ABC,AD is the bisector of /_A , AB=10 cm, AC=5 cm. If BD=4 cm,find CD.

Check whether AD is bisector of angle A " of " Delta ABC in each of the following (i) AB=5 cm, AC=10 cm, BD=1.5 cm and CD=3.5 cm. (ii) AB=4 cm, AC=6 cm, BD=1.6 cm and CD=2.4 cm.

Draw ABC in which /_A=70^(@),AB=4cm and AC=6cm .Measure BC.
