Question

find the value of x in each case.plese it is important so give me correct answer.​

Answer 1

Question is incomplete

Answer 2

Angle DBC=40
Angle EAC=x
Since,AC=BC
AngleBAC=AngleEBC(angles opposite to equal sides are always equal)
AngleDBC=AngleACB(alternative interior angles)
Therefore, in triangle ABC,
Sum of all angles in a triangle =180
x+x+40=180
2x+40=180
2x=180-40
2x=140
x=140/2
x=70

Hope it will help you!!
