Question
the length of a shadow of a building is 26 m. the distance from the top of the building to the tip of the shadow is 32 m. find the height of the building. if necessary, round your answer to the nearest tenth.
Step1: Aplicar el teorema de Pitágoras
Sea $h$ la altura del edificio. El triángulo es rectángulo, así que:
$$h^2 + 26^2 = 32^2$$
Step2: Calcular los cuadrados de los lados
$$h^2 + 676 = 1024$$
Step3: Despejar $h^2$
$$h^2 = 1024 - 676 = 348$$
Step4: Calcular la raíz cuadrada
$$h = \sqrt{348} \approx 18.65$$
Step5: Redondear a la décima
Redondeamos al valor más cercano: $18.7$
