Answer 1

x = 25°

Explanation:

Here given a straight line whose angle equals to 180°

2x + 10 + 4x + 20 = 180

group terms like this ↓

2x + 4x + 10 + 20 = 180

simplify all variables ↓

6x + 30 = 180

changing sides changes addition to subtraction ↓

6x = 180 - 30

6x = 150

changing sides changes multiplication to division ↓

x = 150/6

final answer ↓

x = 25°

Answer 2

x = 25

Explanation:

Angles on a straight line add up to 180°

`\implies (2x + 10) + (4x + 20) = 180`

`\implies 2x + 10 + 4x + 20 = 180`

`\implies 6x + 30 = 180`

`\implies 6x =150`

`\implies x= 25`
