Answer 1

Answer:

angle C = 70

hope it helps you✌

Answer 2

Answer:

55°

Step-by-step explanation:

let the angle a,c = x

70° + x + x = 180° (angle sum property)

2x + 70° = 180°

2x = 180° - 70°

2x = 110°

x = 110° / 2

x = 55°

Each angle = 55°

<C = 55°

CHECKING = 70° + 55° + 55°

= 180°

hope it helps ✌️
