A -------------|D

There are diagonal bisectors inside the rectangle but I could not draw them in. The diagonals are DB and CA and the point in the middle is E.

Since ABCD is a rectangle, the diagonals are the same length, and bisect each other.

Thus, EB = EC and the triangle BCE is isosceles, making m<DBC = m<ACB

So,

10x = 4x^2

10 = 4x

x = 5/2 = 2.5

<DBC = 25°

<ACB = 25°
