Answer: x=50
Explanation:-
Exterior angles of all polygons add up to 360 degrees.
So, x+20+x+40+2x+2x=360
x+x+2x+2x+20+40=360
6x+60=360
6x=360-60
.:6x=300
x=300/6
x=50
Answer:
81 cars
756 trucks
63 wheelers
Step-by-step explanation:
1 mile = 5280 feet
So the jam is 10 miles = 52800 feet
Cars' length = 2 % of the 52800 = 1056 feet
Trucks' length = 29% of the 52800= 15312 feet
Wheelers' length = 9%of the 52800= 4752 feet
Average car is 13 feet in length
The number of cars = 1056 feet/13= 81.23 almost 81 cars
The average truck is 20 feet in length
Number of trucks in 15312 feet=15312 feet/20= 765.6= 756 trucks
The average 18 wheeler is 75 feet in length.
Number of wheelers in 4752 feet= 4752 feet/75= 63.36= 63 wheelers
Step-by-step explanation:
Answer:
length = 9 cm
Step-by-step explanation:
perimeter = p =26 cm
width = w= 4 cm
perimeter of a rectangle= 2*w+2*L
L= length
so we have:
26 = 2*(4) +2*L
26= 8 +2L
26-8 = 2L
18 = 2L
L= 18/2
L =9 cm = length
