Final answer:
The value of x in the given triangle is 19.5°.
Step-by-step explanation:
The sum of the angle measures of any triangle is always 180°. In this case, we have (x + 17)° = 36.5°. To find the value of x, we can subtract 17 from both sides of the equation. This gives us x° = 36.5° - 17° = 19.5°. Therefore, the value of x in the given triangle is 19.5°.
