Answer:
AC = 6
Step-by-step explanation:
y is the dimension of the horizontal segment (see the attached image).
The hypotenuses are the same dimension, so:
(x+4)^2=(x/2)^2+y^2
(3x-8)^2=(x/2)^2+y^2
So,
(x+4)^2 = (3x-8)^2
x+4 = 3x-8
x-3x = -8-4
-2x = -12
x = 6
And x is the dimension of the segment AC.
H is 2t
h + t = 84
2t + t = 84
3t =84
t = 28

Answer: 12.1 meters
Step-by-step explanation:
This is a rectangular fence so it represents a rectangle.
Fencing the garden will require going around it therefore you are looking for the perimeter.
Perimeter of a rectangle = (2 * Length) + ( 2 * Width)
= (2 * 315) + ( 2 * 290)
= 1,210 cm
Convert to meters:
A meter is 100 centimeters
= 1,210 / 100
= 12.1 meters
Finding an arc length requires knowing a bit about the geometry of a circle. Since the arc is a portion of the circumference, if you know what portion of 360 degrees the arc’s central angle is, you can easily find the length of the arc.
