Answer:

bac = 60°

please mark as brainliest answer

Answer 2

Step-by-step explanation:

As by the property,

AB=AC, So angle opposite to equal side in a triangle are equal, hence angle ABC = angle ACB

DE and BC are parallel so by the property

the sum of angle between two parallel side is 180°

hence,

angle DEC + angle ACB = 180°

110° + angle ACB = 180°

angle ACB = 70°

angle ABC = angle ACB,

angle ABC = 70°

sum of all three angles in a triangle is 180°

angle BAC + angle ABC + angle ACB = 180°

angle BAC + 70° +70° = 180°

angle BAC = 180° - 140°

angle BAC = 40°
