Question

D is a point on AB, AC=7, AD=6, BC=18

What is the length of DB?

A. 5

B. 12

C. 19

D. 25

Answer 1

Length of DB = 19 (Approx)

Explanation:

Given:

AC=7

AD=6

BC=18

Find:

Length of DB

Computation:

AB = AD + DB

AB = 6 + DB

AC + BC ≥ AB

7 + 18 ≥ 6 + DB

19 ≥ DB

Length of DB = 19 (Approx)
