Step-by-step explanation:
Angle ACB = 180° - 105°
= 75°
Angle CAB = 180° - ( 70° + 75°)
= 180° - 145°
= 35°
Angle CAE = 180° - 35°
= 145°

Answer:
x=145°
Step-by-step explanation:
see in ∆abc
b=70°
so c=180°-105°[linear pair]
c=75°
then ∆abc=70°+75°+x=180°
∆abc=145+a=180°
∆abc=a=180°-145°=35°
x=180-35=145°
