The height of an equilateral triangle equals 3√2 times the side length. Using 74 for the square root of 3, what is the approximate height in meters of an equilateral triangle with a side length of 8 meters?
The height of an equilateral triangle equals 3√2 times the side length. Using 74 for the square root of 3, we can calculate the approximate height.
Height = 3√2 * side length
Height = 3(74) * 8
Height = 222 * 8
Height = 1776
Therefore, the approximate height of an equilateral triangle with a side length of 8 meters is 1776 meters.
The diagonal of a square equals 2–√ times the side length. Using 1.4 for the square root of 2, what is the approximate length in feet from one corner to an opposite corner of a square park that is 700 feet on a side?
The diagonal of a square equals 2–√ times the side length. Using 1.4 for the square root of 2, we can calculate the approximate length from one corner to an opposite corner of a square park that is 700 feet on a side.
Diagonal = 2–√ * side length
Diagonal = 2(1.4) * 700
Diagonal = 2.8 * 700
Diagonal = 1960
Therefore, the approximate length from one corner to an opposite corner of the square park is 1960 feet.
