The figure shown is a rhombus. If the measure of angle DAB = 115 degrees, what is the measure of angle ADE?

Let AC and BD meet at E (the diagonals intersect at E). In a rhombus opposite angles are equal, so
angle D = 360° − 2·115° = 65°.
Each diagonal bisects the angles it meets, so BD (hence DE) bisects angle D. Therefore
angle ADE = 1/2·65° = 32.5° = 65/2°.
