Question

find the unknown side of the triangle. the length of the unknown side is

Explanation:

Step1: Aplicar el Teorema de Pitágoras

$$a^{2}+b^{2}=c^{2}$$
Donde \(a = 15\), \(b = 20\) y \(c\) es el lado desconocido.

Step2: Sustituir valores

$$15^{2}+20^{2}=c^{2}$$
$$225 + 400 = c^{2}$$
$$625 = c^{2}$$

Step3: Calcular \(c\)

$$c=\sqrt{625}$$
$$c = 25$$

Answer:

25
