Answer:
180.8
Step-by-step explanation:
1. Add all the numbers
2. Divide the sum by 5
3. you get the answer
20% of 3km is 0.6 Kilometer
DC/AC=EC/BC
x/(x+3)=10/16
10(x+3)=16x
10x+30=16x
30=6x
x=5
DC=x=5
DC=5 units long
10/16=DE/AB, DE=y
10/16=y/10
16*y=10*10
y=6.25≈6.3
DE≈6.3
(-5, 2 ) means x = -5 and y = 2
so answer is <span>point D</span>
