Answer:

x = 85° , y = 55°

Explanation:

x and 85° are vertically opposite angles and are congruent ( equal ), so

x = 85°

the sum of the 3 angles in Δ ABC = 180° , that is

x + y + 40° = 180° ( substitute x = 85° )

85° + y + 40° = 180° ( simplify left side )

y + 125° = 180° ( subtract 125° from both sides )

y = 55°
