Answer: The answer is greater than (>).
Step-by-step explanation: We are to find the relationship between AD and EC in the given figure.
In ΔABD and ΔBEC, we have
∠DBA = 30°, ∠EBC = 25°,
AB = BC = 10 units,
BE = BD = 8 units.
Since ∠DBA > ∠EBC, so the sides opposite to them will also follow the same pattern.
That is
side opposite to ∠DBA > the side opposite to ∠EBC.
So, AD > EC.
Thus, the required sign is greater then (>).
