Question

AB perpendicular to CD ,AD is the bisector of angle BAE,
AB=3cm and AC = 5 cm FFindCD

as soon as POSSIBLE

Answer 1

Step-by-step explanation:

FROM TRIANGLE ABC,

AC^2=AB^2+BC^2

5^2=3^2+BC^2

25=9+BC^2

BC^2=25-9

BC^2=16

BC=4

GIVEN AB BISECTS CD

THEREFORE

ANGLE 'A' IS 90°

HENCE ACD IS A RIGHT ANGLED TRIANGLE

CD^2=CA^2+AD^2--------->CLUE

FIND ACD.
