Final answer:
The measure of the exterior angle opposite to the remaining interior angle in a triangle where two of the angles are 60 and 70 degrees, would be 130 degrees.
Step-by-step explanation:
In order to find the measure of the exterior angle opposite in a triangle, first we need to understand how angles in a triangle work. In any triangle, the sum of interior angles is always equal to 180 degrees. Since you already have two interior angles of 60 and 70 degrees, the third angle would be 180 - (60 + 70) = 50 degrees. This third angle is the interior angle opposite to the exterior angle we are trying to find. The exterior angle of a triangle is equal to the sum of the two non-adjacent (the two 'other') interior angles. Therefore, the measure of the exterior angle opposite to the 50-degree angle would be 70 + 60 = 130 degrees.
