Question

BD is angle bisector AB = 10 , BC=15 ,AD=6. find DC​

Answer 1

$\tt\LARGE{\red{Answer:-}}$

DC = 9

$\tt\LARGE{\orange{Explanation:-}}$

$\tt\LARGE{\black{Given:-}}$

BD is a bisector, AB= 10, BC= 15, AD= 6

By BPT theorem,

AD/DC = AB/ BC

6/x = 10/15

10x = 6 × 15

10x = 90

x = 9

Therefore, the value of DC is 9.
