Olin [163]

Answer:

(a) La altura del monumento en metros es de aproximadamente 8.544 m

(b) La distancia recorrida por Mariana y su familia desde Quito a Mompiche en metros es 426,200 m

Step-by-step explanation:

(a) La distancia del que toman la foto desde la base = 300 cm

La distancia diagonal de su rostro al fotógrafo = 800 cm.

Según el teorema de Pitágoras, la altura, h = √ ((800 cm) ² + (300 cm) ²) ≈ 854.400374532 cm

La altura del monumento, h ≈ 854,4 cm

La altura del monumento en metros, h ≈ 8.544 m

(b) La distancia total recorrida por Mariana y su familia desde Quito a Mompiche, d = (338.72 + 34.36 + 53.12) km = 426.2 km

La distancia recorrida en metros, d = 426,2 km × 1.000 m / km = 426.200 m

La distancia recorrida por Mariana y su familia desde Quito a Mompiche en metros, d = 426,200 m
