Given that -
- AB|| DE
- Angle ACB = 53°
- Angle CDE = 45°
- Angle B = X
- Angle E = 3y +1
Now AB||DE then
Angle ABC = Angle CDE ( alternate angle)
So value of X is 45°
Now in ∆ ABC
Angle A + B +C = 180°
[ Interior angle sum property]
A + 45° + 53° = 180°
Now angle A is the alternate angle of angle E
So angle A = angle E
A = 3y+1
→ 3y+1 + 98° = 180°
→ 3y = 180-99°
→ 3y = 81°
→ y. = 27°

Answer:
Step-by-step explanation:
ACB=DCE.....(opposite angles)
Therefore, 53°=DCE
Now, ABC=CDE....( alternate angles)
Therefore, x°=45°
Sum of all triangles =180°
Thus, 53+45+A=180
98+A=180
A=180-98
=72°
Thus BAC=DEC...(alternate angles)
72°=DEC
