Answer 2

Answer:

The value of BD is 12.5 cm

Step-by-step explanation:

Step 1:

Since $24 ^ 2 + 7 ^ 2 = 25 ^ 2$

Step 2:

Which means $AB ^ 2 + BC ^ 2 = AC ^ 2$

Step 3:

Thus this triangle is right angle and  AC is the diameter of circumcircle of the triangle ABC.  

Step 4:

Therefore BD will be radius of the circumcircle of triangle ABC as D is the mid point of AC.

Step 5:

Thus BD = AC / 2  = 25 / 2 = 12.5 cm
