Answer:

x = 120°

Explanation:

The sum of the 3 angles in a triangle = 180°

In Δ ADB

∠ ABD = 180° - (55 + 25)° = 180° - 80° = 100°

∠ ABD and ∠ DBC are adjacent and supplementary, thus

∠DBC = 180° - 100° = 80°

The external angle of a triangle is equal to the sum of the two opposite interior angles.

x is an exterior angle of Δ EBC, thus

x = 80° + 40° = 120°
