Answer:
7
Step-by-step explanation:
Let's say our sum is s.
s = 10 right angles
a right angle is 90 degrees
s = 10 (90)
s= 900
Given the amount of sides in a polygon (n), the sum of the interior angles is equal to
(n-2) * 180
Therefore, the sum of the interior angles is equal to
(n-2) * 180 = 900
divide both sides by 180 to help isolate n
n-2 = 5
add 2 to both sides to isolate n
n = 7
P=2,900,000 is the population in 1950
I hope it's correct have a nice day
Answer:
7.8cm
Step-by-step explanation:
1cm rep10km
Xcm rep78km
Cross multiply
10xcm=78*1
Xcm=78/10
X= 7.8cm
Since you already know the radius multiply it by itself(20*20=400)then multiply that amount by 3.14.(formula: 3.14*(radius*radius)
