Answer:
Here both triangles are congruent
Explanation:
<CAB = <EAD ( being vertically opposite angles )
And as we know that they are congruent triangles so
<ADE = <ABC ( Corresponding angles of congruent triangle)
<ADE = 86°
<EAD = 53°
<AED = x
Now in ADE
<ADE + <EAD + <AED = 180° ( being sum of angles of triangle )
86° + 53° + x = 180 °
139° + x = 180°
x =180°- 139°
Therefore x = 41°
