The sum of the tree angles is 180 degrees, so:
First+Second +Third=180 degrees Subtract First from each side.
Second+Third=180 degrees-First Subtract Second from each side
Third=180 degrees-First-Second Plug in values
Third=180 degrees-58 degrees-52 degrees
Third=70 degrees ANSWER: The third angle measures 70 degrees.
