Answer: perimeter = 26.5
Area = 106
Step-by-step explanation:
The given polygon is an octagon. The apotherm which is the perpendicular line from the midpoint of the octagon is 8,
The formula for determining the area of a polygon is expressed as
Area = a² × n × tan 180/n
Where n represents the number of sides of the polygon.
n = 8
Therefore,
Area = 8² × 4 × tan(180/8)
Area = 256 × tan 22.5
Area = 106
The formula for determining the perimeter of a regular polygon is
P = 2 × area/apotherm
Perimeter = 2 × 106/8
Perimeter = 26.5
Answer:
Answer 7
Step-by-step explanation:
This depends on setting up a proportion
5:45 :: 3: 3 + 2x + 10
You can reduce 5 / 45
5/45 = 1/9
1:9 :: 3:3 + 2x + 10
1:9 :: 3: 2x + 13
1/9 = 3/(2x + 13) Cross Multiply
2x + 13 = 3*9
2x + 13 = 27 Subtract 13
2x + 13 - 13 = 27 - 13
2x = 14 Divide by 2
2x/2 = 14/2 Divide
x = 7
