No, it is #180^o#

Explanation:

The angles of any triangle add up to 180 degrees. To prove this point, duplicate the triangle and connect them together at the longest sections of the triangle. It will form a quadrilateral, which always has 360 degrees; divide that into 2 parts, and you get 180 degrees
