help me with this plzz

Answer 1

angle Dab is also 35 and ac is also 40because they are isosceles triangle so the one side is equal to another side and one angle is equal to the opposite angle then we find the angle B and angle C by angle sum property angle b is 35 +35 +b= 180 b is 110 and c is 100 and by linear pair property we can find the inner part of Angle B and angle C that is angle b is equal to 70 and angle C is equal to 80 angle x is equal to 30
