128°
Explanation:
Sum of the interior angles at a point is always 360°.
Therefore, sum of the measures of the interior angles at vertex I and vertex J is equal to 360° - 38° = 322°.
Now, we know that the angle at vertex J is 38°, therefore, the angle at vertex I is 322° - 38° = 284°.
Therefore, the sum of the measures of the interior angles at vertex I and vertex J is 284° + 38° = 322 + 38 = 128°.
What is the sum of the measures of the interior angles at vertex I and vertex J ?
