Answer 1

x = 15

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.

• 
  `(9x)+(37+8)=180`
• 
  `9x+45=180`

Step 2: Subtract 45 from both sides.

• 
  `9x+45-45=180-45`
• 
  `9x=135`

Step 3: Divide both sides by 9.

• 
  `9x/9=135/9`
• 
  `x=15`

Therefore, x = 15!
