Answer:
x = 13°
Explanation:
Because of the given congruency,
Angle A = Angle D = 63°.
Angle C = 52°
Angle B = Angle E = 5x
Now, In Triangle ABC,
Angle A + Angle B + Angle C = 180°.
63° + 5x + 52° = 180°
115° + 5x = 180
5x = 65°
HOPE IT HELPS!!!
angle A = angle D
angle C common angle
angle E = 180 - 63 - 52
5x = 65
x = 13deg
