Answer:
18.03
Step-by-step explanation:
So first David went 200m west. I drew a line that went to the west. Next he went 125m north. I drew a line that went north. The question is asking you how far away he is from his starting point. I drew a triangle and connected those two points from where he began. So to find the length or missing side, you need to use an equation known as the pathaegorean theorem. A²+ B²+ C². 125+200 is 325. The square root of 325 is 18.0277. However, they ask us to round to the nearest hundredth. So that number would you round to 18.03 ( since the seven makes the two go up).
