In right triangle ABC what is the arithmetic mean (average), in degrees, of the measures of the two smallest angles?

Explain how the answer is 45 degrees.

  • Math -

    A triangle has a total of 180 degrees.
    Since the right angle = 90 degrees.

    There is a total of 90 degrees left for the other two angles.

    Their sum divided by 2 gives the arithmetic mean of 45 degrees
