Question

Please help me solve for x in this picture, thank you

Answer 1

Answer:

x = –10

Step-by-step explanation:

The angles are supplementary

(x + 75) + (x + 125) = 180

Combine like terms

2x + 200 = 180

Subtract 200 from both sides

2x = -20

divide both sides by 2

x = –10

Answer 2

Answer:

x = -10

Step-by-step explanation:

These are known as same-side interior angles and they are supplementary.

$x+125+x+75=180\\\\2x+200=180\\\\2x=-20\\\\x=-10$
