제가 문제를 막 풀다가 헷갈리는 문제 2개가 나와서 해결해주시면 감사하겠습니다.
(그림으로 해결 방법을 설명 해주시면 더 감사하고요 감사내공 꼭 드리겠습니다 ~ !)
Q : Heather and Kim took part in a scavenger hunt. They begin the hunt at the same starting point. Heater walks 20m north, then 50m east to find her first treasure. Kim walks 70m south, then 30m west and stops.
a) How far is each girl from the starting point ?
b) How far the girls from each other ?
c) Suppose Heather looks directly at kim. Will the starting point be in her direct line of sight? Explain
아랫문제는 Slope에 연관된 것 같네요.
Q: One safety standard for a ladder is that the distance from the wall to the base of the ladder should be one-quarter of the distane up the wall to the top of the ladder.
a) What is the slope of a ladder that is leaning safety?
b) A ladder is 2.6m long. The top of the ladder touches a window 2.5m above the ground. What is the slope of the ladder? Is the ladder safe?
c) Choose either part a or b write to explain how you determined the slope.
