Answer:

120

LET EACH ANGLE BE X

X + X + X = 180

3X = 180

X = 180/3

X = 60

ANGLE ACB + ANGLE ACD = 180

60 + ACD = 180

angle \: acd \:  = 120

hope it helps...

let \: each \: angle  = x

by \: angle \: sum \: property

→x + x + x = 180

→3x = 180

\\→x =  \frac{180}{3}

angle \: ACB + angle \: ACD = 180

⟹60 + angle \:ACD = 180

⟹angle \:ACD = 180 - 60

⟹angle \:ACD= 120
