89760÷5280=17 is how much feet is in a mile
Answer:
n = -8
Step-by-step explanation:
Those are adjacent angles. They will equal 180 degrees since they both ly on the same straight line. Straight line= 180 degrees.
10x-20+6x+8=180
Add 20 to both sides.
10x+6x+8= 200
Combine like terms.
16x=192
Divide both sides by 16.
x=12
I hope this helps!
