To solve for x, we need to set up an equation based on the given information. Since the angles are adjacent and inside a 90° angle, we know that their sum must equal 90°.
We can write this as:
(x + 4)° + (3x + 2)° = 90°
To solve the equation, combine like terms:
4x + 6 = 90
Next, subtract 6 from both sides:
4x = 84
Finally, divide both sides by 4:
x = 21
Therefore, x = 21.
