Answer:
all the angles of the pentagon do not add up to 540
Step-by-step explanation:
total degree in a shape
180 × (n-2) where n is the number of side
a pentagon has 5 sides so
180 × (5-2)
= 540
100+105+72+126+127= 530
all the angles of the pentagon do not add up to 540
It will take the first car 5.5 hours to catch up to the second car.
Step-by-step explanation:
Speed of second car = 55 miles per hour
As the car has started one hour before; it has already traveled
Distance = Speed * Time
Distance = 55*1 = 55 miles
Let,
x be the number of hours.
Distance covered in x hours = 55x
S(x) = 55x+55
Speed of first car = 65 miles per hour
Distance covered in x hours = 65x
F(x) = 65x
For catching up;
F(x) = S(x)
![65x=55x+55\\65x-55x=55\\10x=55](https://tex.z-dn.net/?f=65x%3D55x%2B55%5C%5C65x-55x%3D55%5C%5C10x%3D55)
Dividing both sides by 10
![\frac{10x}{10}=\frac{55}{10}\\x=5.5](https://tex.z-dn.net/?f=%5Cfrac%7B10x%7D%7B10%7D%3D%5Cfrac%7B55%7D%7B10%7D%5C%5Cx%3D5.5)
It will take the first car 5.5 hours to catch up to the second car.
