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).

Answer: 20%
Step-by-step explanation:
First you have to take 1008 and subtract 806.4. Once you get that answer you put it into a division problem. So answer over the first number, being 1008. Then multiply that answer by 100. and that is your percentage.
Answer:
58°
Step-by-step explanation:
<MQR = <XQL (vertically opposite angles)
28 + 5b = 70 - 2b
28 - 70 = -2b - 5b
-42 = -7b
-42/-7 = b
6 = b
<MQR = 28 + 5b
= 28 + 5(6)
= 28 + 30
= 58°
