    Answer:The sum of the interior angles of a triangle are equal to 180o. To find the third angle of a triangle when the other two angles are known subtract the number of degrees in the other two angles from 180o.

    Example: How many degrees are in the third angle of a triange whose other two angles are 40o and 65o? Answer: 180o - 40o - 65o = 75o
