Identify the whole-number measure of segment AD¯¯¯¯¯¯¯¯

that would create △ABD
and △ACD
as shown.

An illustration shows a rhombus where the vertices are labeled as follows: A on the top vertex, B on the left, C on the right, and D at the bottom. A dashed line is drawn from A to D. The sides are labeled as follows: A C is labeled as 5, A B as 4, B D as 8, and C D as 15.

Apologies for the mistake. The correct whole-number measure of segment AD¯¯¯¯¯¯¯¯ that would create △ABD and △ACD is indeed 11. Thank you for pointing out the error.
