astraxan [27]

Answer:

x = 45

Step-by-step explanation:

The angles with (2x + 45) and x are supplementary angles, meaning they add up to 180°. We can write this statement as an algebraic equation of 2x + 45 + x = 180 and solve it.

Step 1: Combine like terms.

  • (2x+x)+45=180
  • 3x+45=180

Step 2: Subtract 45 from both sides.

  • 3x + 45 - 45 = 180 - 45
  • 3x = 135

Step 3: Divide both sides by 3.

  • 3x/3 = 135/3
  • x = 45

Step 4: Check if solution is correct.

  • 2(45) + 45 + 45 = 180
  • 90 + 90 = 180
  • 180=180

Therefore, x = 45.

Have a lovely rest of your day/night, and good luck with your assignments! ♡
