Answer: i) ∠x + 80°+25°= 180°( angle sum property)
105°+∠x= 180
∠x= 180°-105°= 75°
ii) ∠x + ∠x + 40°= 180°( angle sum property)
∠2x + 40°= 180°
∠2x= 180°-40°= 140°
∠x= 140/2= 70°
iii) ∠BAE + ∠BAC= 180°( Linear pair)
110°+∠BAC= 180°
∠BAC= 180°-110°= 70°
∠ACD(120° one angle) = ∠BAC + ∠x ( Exterior angle property of triangle)
120°=70° + ∠x
∠x= 120°-70°= 50°
Hope it helps!!!!
Plz mark it as the brainliest!!!
