The first thing that I did was to find the angles of A and B.Sin angle A = 12/14 Sin A = 58.99degrees, and I rounded to 59, so angle B = 31 degrees. I found the value of AC using Pythagorean theorem. AC = sq rt 52.

Sin A = x/sq rt 52.x = 6.18.

6.18 is CD.

Tan B = 6.18/x

x = 6.18/tan 31= 10.28

So DB = 10.28
