Find the measure of the side of the right triangle whose length is designated by a lowercase letter b. WebNov 28, 2012 · The lengths of the sides of a right triangle are related by the Pythagorean Theorem, which states a 2 + b 2 = c 2, where a and b are the lengths the two legs and c is the length of the hypotenuse. Using the information you have, you want to solve 40 2 + b 2 = 43 2 to get b = 249 ≈ 15.78.
