Answer:
10 sides,that is, a decagon or 10gon
Step-by-step explanation:
If the exterior angle is 36° then numbers of sides=
Therefore
n=360°÷36°=10
50,000 because if the number is lower than 5 than you round down and thing higher than 5 is rounded up
Answer:
s=25
Step-by-step explanation:
The solution is (5,2)
Step-by-step explanation:
From the third column the equation for sum of equivalent system is given as;
8x = 40
divide both sides by 8 to get value of x
8x/8 = 40/8
x=5
Using the value of x in the fifth column's first equation will be;
4x +4y =28
4(5) + 4y =28
20 +4y =28
4y= 28-20
4y=8
divide both sides by 4 to get y
4y/4 =8/4
y=2
The solution is x=5 and y=2 written as (5,2)
