Answer:

The measure of the third angle is
11\°

Explanation:

we know that

The sum of the interior angles in a triangle must be equal to 180 degrees

Let

x ---> the measure of the third angle in degrees

The linear equation that represent this situation is


x+102\°+67\°=180\°

solve for x


x+169\°=180\°


x=180\°-169\°


x=11\°
