For a right triangle, the Pythagorean theorem can be used to calculate the sides of the triangle. This theorem is expressed as: c^2 = a^2 + b^2. From th problem, we are given c which is the hypotenuse and the other leg which we will assign as the leg a. Calculation is as follows:
c^2 = a^2 + b^2
(155cm)^2 = (124cm)^2 + b^2
b= 93 cm
