Answer:
d) 60°
Step-by-step explanation:
In ∆ ABC.
<A + <B + <C = 180
<A + 180 -120 + 180 - 120 = 180
<A + 120 = 180
<A = 60

Answer:
Angle A = 60°
Step-by-step explanation:
Angle ACB= 60° ~{Linear pair}
Angle ABC=60° ~{Linear pair}
Sum of all angles= 180°
Let angle A = x
60+60+x = 180
x = 180-120
x= 60°
Angle A = 60°
