I’m confused on this one
serious [3.7K]
The answer is 13.

Because this is a kite, the diagonals intersect perpendicularly or with a 90° angle.

In the triangle DIC, which is a right triangle, the legs are 5 and 12. To find the hypotenuse, we use Pythogarean theorem:
{a}^{2}  +  {b}^{2}  =  {c}^{2}
Plug in the givens:
{5}^{2}  +  {12}^{2}  =  {c}^{2}
Take the squares:
25 + 144 = 169  =  {c}^{2}
Take the square root of both sides:
\sqrt{169}  =   \sqrt{ {c}^{2} }  \\  \\ c = 13
We find the line segment DC. In the question it says "BD = DC". So BD is equal to 13.
