Answer:
x = 20
Step-by-step explanation:
Each side would be 60. 60/3 would be 20. So x = 20
Answer: x = 56
It’s a supplementary angle
Step-by-step explanation:
It’s a supplementary angle if their measures add to 180 degrees
is the equation
2x + 68 = 180 degrees
2x = 180 -68
2x = 112
x = 112/2
x = 56
well you know that the yellow rope is 18' shorter then the white rope X 2,
so you would take 101/2 feet and add 18 inches, then you would need to divide that by two to get how long the white one is.
10 1/2 feet + 18 inches = 12 feet
12 feet divided by 2 is 6 feet
Answer:
18581.16
Step-by-step explanation:
The area of each of the shale can be calculated as
distance between each point = x
The area of the regular Dodecahedron
A = ![\sqrt[3]{25+10\sqrt{5} } a^{2}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B25%2B10%5Csqrt%7B5%7D%20%7D%20%20%20a%5E%7B2%7D)
where a = number of edges = 30
hence the area of the regular dodecaheron = 18581.16
