Answer
In the figure, DCE is a straight line.
At point B, the angles ∠ABD and ∠ABC form a linear pair.
∴ ∠ABD + ∠ABC = 180°
We know from the figure that ∠ABD = x° and ∠ABC = 115°
Substituting the values in above, we get:
⇒ x + 115° = 180°
⇒ x = 180° - 115°
⇒ x° = 65°
At point C, the angles ∠ACB and ∠ACE form a linear pair.
∴ ∠ACB + ∠ACE = 180°
We know from the figure that ∠ACB = y° and ∠ACE = 132°
Substituting the values in above, we get:
⇒ y° + 132° = 180°
⇒ y° = 180° - 132°
⇒ y° = 48°
The values are x° = 65° and y° = 48°.
