Name__________________________________
If AD = 10, DC =6, and ED = 15, find DB.
If AB= 4x2+ 12 and AC =3x2+ 28, find AB.

2. If BE = 14, FC =6, and EA = 4, find AF.
If CD = 6, AB =9, find AC.

3. = 35o
= 40o
FC = 6
= 90o
DC = 45
DB = 4
AC = 3
AB = 76

4. = 120o
= 108o
If ED = 10, DB =30, and AD = 15, find DC.
DC = 20
If AB= 7x-9 and AC = 4x + 15 find AB.
AB = 47

5. = 55o
If BE = 4, EA =3, and AF = 2, find FC.
FC = 11.5
= 100o
If AC = 2, AB = 8, find CD.
CD = 2 √5
