Answer 1

80 degree

Explanation:

Sum of all angles inside a triangle is 180.

70 + 30 + x = 180

x = 180- 70 - 30

x = 80

Answer 2

`\huge\boxed{\sf x = 80\°}`

Explanation:

Statement:

• Interior angles of a triangle add up to 180 degrees.

So,

30 + 70 + x = 180

100 + x = 180

Subtract 100 to both sides

x = 180 - 100

x = 80°
