Question

In a triangle ABC, AD is the bisector of angle A, meeting side BC at D.
If AD = 5.6 cm, BC = 6 cm and BD = 3.2 cm, find AC.​

Answer 1

Answer:

AC=6.26cm

Step-by-step explanation:

We are given that In a triangle ABC, AD is the bisector of angle A, meeting side BC at D. If AD=5.6cm, BC=6cm and BD=3.2cm.

Since, DC=BC-BD

⇒DC=6-3.2

⇒DC=2.8cm

Now, from ΔADC, we have

(AC)^{2}=(AD)^{2}+(DC)^{2}

Substituting the values, we get

(AC)^{2}=(5.6)^{2}+(2.8)^{2}

(AC)^{2}=31.36+7.84

(AC)^{2}=39.2

AC=6.26cm

Thus, the value of AC will be 6.26 cm.

Answer 2

Answer:

Step-by-step explanation:we can find it by the property of bisector of an angle.
