An iron dinner bell is in the shape of an equilateral triangle with a side length of 8 5/8 inches. Find the length of the rod us
ed to create the bell
1 answer:
Answer:
25 7/8inches
Step-by-step explanation:
The length of the rod is equal to the side length of the equilateral triangle
Let the length of the rod be x
Since an equilateral triangle has all its sides equal, its perimeter is expressed as;
P = x+x+x
P = 3x
Given x =8 5/8
P = 3(69/8)
P = 207/8
Express as mixed fraction
P = 25 7/8 inches
Hence the length of the rod used to create the bell is 25 7/8inches

Answer:
Here's what i know:
x + y = 23
3y / 20 =x
Here we can use substitution to help find our answer:
y + 3y/20 = 23
20y/20 + 3y/20 = 23
23y/20 = 23
23y = 23 * 20
y = 23 * 20 / 23
y = 20
x + 20 = 23
x = 3
Answer:
maybe 90*
