답을 찾으려면 축척 도면이 아닌 삼각법을 사용해야 합니다. 라울은 주요 도로 중 하나에 높은 탑이 있는 도시를 방문하고 있습니다. 그가 묵고 있는 호텔도 같은 길에 있습니다. 라울은 호텔에서 출발하여 타워를 지나 호텔에서 정확히 1km 떨어진 이정표 M에서 멈춥니다. 라울은 만보계를 가지고 있으며 이를 사용하여 타워의 높이를 추정할 계획입니다. 라울은 거리계를 눈앞에 두고 탑 꼭대기의 경사각이 11◦ 라는 것을 알아냅니다. 호텔로 돌아와서 그곳에서 탑 꼭대기의 고도 각도를 측정한 결과 20◦ 인 것을 알았습니다. H를 라울의 호텔 위치(주요 도로를 따라)를 나타내고, B를 탑의 기슭을 나타냅니다. 도로는 평평하고 H, B, M은 일직선상에 있다고 가정할 수 있습니다. 다음 문제에서는 각도가 라울의 눈 높이가 아닌 지면에 있는 것처럼 각도를 측정한다는 단순화 가정을 하고, T는 탑의 꼭대기를 나타내며 밑면 B보다 수직으로 위에 있습니다. 삼각형 HTM을 나타내는 이미지를 생성합니다. 점 B를 추가하고 점 B와 T를 점선으로 연결합니다. 위에서 언급한 길이(미터) 및 각도에 대한 정보를 포함하세요. 스케치의 크기를 조정할 필요는 없습니다.
