Answer:
i) 130° = b + 70° (exterior angle property)
b = 130°- 70°
b = 60°
a + b + 70° = 180°(Sum of all the sides of triangle)
a + 60° + 70° = 180°
a = 180° - 130°
a = 50°
ii) 140° = x + x(exterior angle property)
2x = 140°
x = 140°÷2 or 140/2
x = 70°
Step-by-step explanation:
I hope this will help you

(i)
Using Exterior angle property ,
[tex] \angle \: a\: + 130° = 180° \\ \angle \: a = 180 ° - 130° \\ \angle \:a = 50° [/tex]
Using Sum of angles in a ∆ property,
[tex] \angle \: b\: + 70° + 50° = 180° \\ \angle \: b = 180 ° - 120° \\ \angle \:b= 60° [/tex]
(ii)
Using Exterior angle property ,
[tex] \angle \: x\: + \angle \: x\: = 180° \\ \angle \: 2x= 180 ° \\ \angle \:x= \frac{180° }{2} \\\angle \:x = 90 °[/tex]
