The Pythagorean theorem shows us that the measure of the sides in a right triangle can be calculated using the formula a^2 + b^2 = c^2. Using this formula, and filling in the blank, we can conclude that the other leg measures 8 cm.
(1 + 1/3)^2 - 2/9
= (3/3 + 1/3)^2 - 2/9
= (4/3)^2 - 2/9
= 16/9 - 2/9
= 14/9
