Answer:
38.5
Step-by-step explanation:
b^2= 29^2+20^2-2×20×29× Cos 102
b^2=841+400-1160 (-0.2079)
=1241- 241.164
b^2=1482.164
b= square root of 1482.164
AC = 38.5
15 posts plus 2 corner posts = 17 posts. With 17 posts there would be 16 spaces each side.
The space between each is 8 1/8 feet.
The length of one side is the number of spaces multiplied by the distance between each space.
Total length of one side = 16 spaces x 8 1/8 feet = 130 feet
Area = length x width.
It’s a square shape so area = 130 x 130 = 16,900 square feet
Perimeter is the distance around the square, this would be the length of one side x the number of sides.
Perimeter = 130 x 4 = 520 feet
Say x is the smaller of the two:
x/3=y/7
2x+3y=2700
solve and you get that
y=700, x=300
Given two points, the equation of the line in slope form can be obtained using this equation

Now we can name the points
x1 = 2, y1 = 8
x2 = 4 , y2 =9
These coordinates can then be substituted into the equation


x - 2 + 16 = 2y
2y = x - 2 +16
2y = x + 14
Divide both sides by 2
y = x/2 + 14/2

This is the equation in slope-intercept form
where the slope = 1/2
