Question

plz givee me solution fast​

Answer 1

Answer:

Now,

angle BCD = (180-126)° = 54° [Linear pair]

Now,

angle ACD = 1/2 angle BCD

= 54×1/2 = 27°

Hence,angle ACD = 27°.

Answer 2

Answer:

Angle ACD = 27°

Step-by-step explanation:

Angle ABC+Angle BCD = 180°

126°+Angle BCD = 180°

Angle BCD = 180°- 126 = 54°

Angle BCD = 54°

Angle ACD = 1/2 × 54° = 27° ( Since AC is the diagonal and diagonals bisect the angle at vertices)

Hence Angle ACD = 27°
