Answer:
The measure of the third angle is [tex]11\°[/tex]
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
[tex]x+102\°+67\°=180\°[/tex]
solve for x
[tex]x+169\°=180\°[/tex]
[tex]x=180\°-169\°[/tex]
[tex]x=11\°[/tex]
