Answer:
x = 15
Step-by-step explanation:
We can see that the angle with a measure of 37° and the angle with (9x + 8)° form a straight line, so they add up to 180°. This means that 37 + 9x + 8 = 180.
Step 1: Combine like terms.
- [tex](9x)+(37+8)=180[/tex]
- [tex]9x+45=180[/tex]
Step 2: Subtract 45 from both sides.
- [tex]9x+45-45=180-45[/tex]
- [tex]9x=135[/tex]
Step 3: Divide both sides by 9.
- [tex]9x/9=135/9[/tex]
- [tex]x=15[/tex]
Therefore, x = 15!
