A triangle has angles measuring 48° and 67°. Find the measure of the third angle.

The interior angles of a triangle always add up to 180°.

Let the third angle be x.

Set up the equation:
48° + 67° + x = 180°

Add the known angles:
115° + x = 180°

Subtract 115° from both sides:
x = 65°

Therefore, the third angle measures 65°.
