Question

Find the value of x in the angle pair.

Answer 1

`\Large \boxed{\sf x=50}`

Explanation:

Angles on a straight line add up to 180°

`30+3x=180`

Solve for x

`3x=150`

`x=50`

Answer 2

`\huge\boxed{\tt{x = 50}}`

Explanation:

3x + 30 = 180 (Angles on a straight line add up to 180 degrees)

Subtract 30 to both sides

3x = 180 - 30

3x = 150

Divide 3 to both sides

x = 150 / 3

x = 50

`\rule[225]{225}{2}`

Hope this helped!
