Hello!
This is a question relating the interior angle sum of a triangle.
The interior angle sum of a triangle will be 180 degrees.
Since we are given two angle measures, we can set up an equation to find the unknown angle measure.
[tex]35+73+x=180[/tex]
[tex]x=180-35-73[/tex]
[tex]x=72[/tex]
The third angle's measure is 72 degrees.
Hope this helps!
