Answer:
1. <em>L = 3D +59</em>
2. 158 miles
Step-by-step explanation:
For the second part:
Since each day 3 miles of the road is being added, we can simply multiply the number 33 by 3, getting 99. If the road started with 59 miles, we need to add 59 to 99, getting 158 miles.
Answer:
x=15°
Step-by-step explanation:
Angles ∠2 and ∠4 are supplementary, so ∠2+∠4=180°
That equals to 2x+10+4x+80=180.
You can solve that equation to find what <em>x</em> is equal to.
2x+10+4x+80=180
6x+90=180
6x=90
x=15°
