    40 degrees

    Step-by-step explanation:

    The three angles of any triangle always add up to 180 degrees.

    Thus, since we already know 2 angles which add up to 140 degrees, we just need to subtract the two angles we already know from 180 degrees for the third angle.

    180-140=40 degrees.
