Question

QUE.3) FIND VALUE OF X AND Y​

Answer 1

Angle 3 + Angle 4 = 180° (linear pair)

Angle 3 = 180 -110

Angle 3 = 70°

Angle 1 + Angle 2 + Angle 3 = 180 ° ( angle sum property)

x+y+70° = 180 (-eq 1)

AB =AC (given)

Angle 2 = Angle 3 ( angles opposite to equal sides are equal)

y = 70°

Putting value of y in eq 1

x=40°
