Answer:
Sum of exterior angle of polygon=360
Each exterior angle of polygon =24
Number of sides of polygon=\frac{360}{24}
24
360
=15
=> Number of sides of polygon with each angle of 24 is 15.
Step-by-step explanation:
Let x = first plane's speed.
We have the equation:
2 hours * x km/h + 1.5 hours * (x+60) km/h = 3135 km.
3.5 hours*x km/h + 90 km = 3135km
3.5hours*x km/h = 3045km
x = 870 km/h.
The first plane is traveling at 870 km/h, therefore since it is 60 km/h faster, the second plane is traveling at 930 km/h.

Step-by-step explanation:
h = 4(x+3y)+2
h = 4x + 12y + 2
4x = 14y
