rk
orean theorem. if the side length is
Step1: Identificar variables del teorema
Sean $c=25$ (hipotenusa), $a=15$ (cateto), $b$ (cateto desconocido).
Step2: Aplicar el Teorema de Pitágoras
El teorema establece $a^2 + b^2 = c^2$, despejamos $b$:
$$b = \sqrt{c^2 - a^2}$$
Step3: Sustituir valores conocidos
$$b = \sqrt{25^2 - 15^2}$$
Step4: Calcular cuadrados y diferencia
$$25^2=625, \quad 15^2=225$$
$$625 - 225 = 400$$
Step5: Calcular raíz cuadrada
$$b = \sqrt{400} = 20$$
