Um observador, situado num ponto O da margem de um rio, precisava determi- nar, sem atravessar o rio, sua distância até o ponto P, localizado na outra margem. Para isso, marcou com estacas outros pon- tos do lado da margem onde se encontrava, de tal forma que P, O e B ficaram alinhados entre si e P, A e C também. Sabendo que OA é paralelo a BC, OA = 25 m, BC = 40 m e OB = 30 m, qual é a distância, em metros, do observador em O até o ponto P?
