Answer:

The measure of the third angle is $11\°$

Step-by-step 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

$x+169\°=180\°$

$x=180\°-169\°$

$x=11\°$
