The answer is 2/15
6/15 * 5/15 = 30/225 = 6/45 = 2/15
6/15 * 5/15 = 30/225 = 6/45 = 2/15
The length of line BC is 16. 12
<h3>How to determine the value</h3>We have that;
- Line BD = 12
- Line AD = 5
- Line BC = unknown
Let's line BA, using Pythagorean theorem
BA =
BA =
BA =
BA = 13
Now, let's find BC
cos 30 = line BA/ line BC
0. 8660 = 14/ BC
cross multiply
BC = 14/0.8660
BC = 16. 12
Thus, the length of line BC is 16. 12
