Answer 1

Step-by-step explanation:

The angles shown is supplementary because the sum of 123 and 3x is 180.

Thus, the equation formed:

• 123 + 3x = 180°

Subtract 123 both sides:

• 123 + 3x = 180°
• => 123 - 123 + 3x = 180 - 123
• => 3x = 57

Divide 3 both sides:

• => x = 57/3 = 19

The value of x is 19.

Answer 2

It is a linear pair of angles hence supplementary

`\\ \tt\hookrightarrow 123+3x=180`

`\\ \tt\hookrightarrow 3x=180-123`

`\\ \tt\hookrightarrow 3x=57`

`\\ \tt\hookrightarrow x=19`
